This myth was the first entry among those listed as one of the twelve myths that would not be tested in MythBusters: The Explosive Truth Behind 30 of the Most Perplexing Urban Legends of All Time. In an interview for Skeptic magazine, the myth apparently was considered too controversial by Discovery Channel, which thought testing the myth could provoke prisoners to try similar things.
|A prison inmate can kill another inmate from across the hall, using newspaper for a paper crossbow.||Plausible||Jamie and Adam built separate crossbows for the myth and fired a few shots each. Testing proved it is possible to kill someone using a paper crossbow, but it would require a precise shot to a vital spot (such as a jugular vein or eye), which is difficult with improvised weapons such as a paper crossbow. Adam's crossbow achieved a maximum arrow velocity of 91 ft/s (28 m/s), a maximum arrow energy of 7.45 ft⋅lbf (10.10 J), and pierced a dummy's throat one inch (25 mm) deep from a distance of 15 ft (4.6 m) on the first shot. The crossbows each gradually became useless after a few shots, showing that the shooter would only have a few shots to hit a vital spot. Also, the obvious problem exists of getting off one shot or more without being caught in the act.
A visit to a local prison revealed inmates have improvised far more effective weapons in the past, up to and including a hand-made gun with a flash suppressor, firing bullets smuggled into the prison.
Kari, Tory, and Grant tested to see if vodka...
|...can remove cigarette smoke smell from clothes.||Plausible||The difference was noticeable between the control jacket and the one sprayed with vodka before washing. Grant described the control jacket as having an "oaky smell" to it, while on the vodka jacket he could not detect such a smell.|
|...can kill bees like an insecticide.||Busted||The control water killed more bees (two) than vodka, which failed to kill any. The bees sprayed with water went into a comatose-like state and awoke later the next day when they dried off. The bees sprayed with vodka showed no ill effects at all (though they seemed to fly in a weird manner as if they were drunk).|
|...can be used as a bathroom cleaner.||Plausible||Vodka proved to be less effective than a commercial bathroom cleaner, but still serviceable.|
A plane's tail section in a widely circulated photo was shredded by...
|...a chainsaw.||Busted||The slices made by the chainsaw were jagged while the ones seen in the photo were clean slices.|
|...a runaway taxiing plane's propeller.||Confirmed||The full-scale test done with a run-away engine and stand-in tail section produced a result that was almost identical to the shredded plane seen in the photo. The incident was later confirmed as having taken place, the photo coming from a newspaper article in Australia.|
Fire can be started...
|...using the friction caused by rubbing two sticks together.||Confirmed||While the Build Team—in their own words—cheated and used a drill and some gunpowder, with a stick in place of a drillbit, the friction from the drill did light the tinder on fire. This myth was tested legitimately in the 2012 season's "Duct Tape Island" with a bamboo bow drill and duct tape string.|
|...using a bullet.||Confirmed||Earlier tests using modern weaponry (and smokeless powder) were unproductive. Tory then modified an old musket and replaced the bullet with a piece of cloth. When the gun was fired, the black powder (which burns more energetically than smokeless) ignited the cloth, which then ignited the tinder into which it was shot.|
|...using a soda can bottom polished with chocolate.||Confirmed||Chocolate was used to buff out the wear marks and ink marking and give the can bottom a reflective shine that could focus light and produce heat. While the can was not able to light tinder that was held by hand, the rig easily lit when the tinder was secured on a makeshift rig that kept it from moving.|
|...using steel wool and the ends of a battery.||Confirmed||It took several tries, but the ends of the battery eventually heated the steel wool (through electric resistance) enough to light it on fire. A clip from a survivalist TV show with Ron Hood also showed this myth to be confirmed. This is also a requirement for the American Boy Scout Wilderness Survival merit badge.|
|...using ice.||Confirmed||Kari used a globe of specially produced clear ice about half the size of a bowling ball to produce smoke and later fire when she used it as a refractive lens.|
This was the third episode where Myths from previous episodes were revisited, as well as the third episode to focus on just one experiment.
This episode, referred to as the MythBusters Mailbag Special: The Great Archimedes Burn-Off from within the episode itself, saw a retest of the Ancient Death Ray myth after fans of the series contested their original decision. To this end, the MythBusters commissioned a contest, challenging viewers to prove the myth plausible.
Candidates could enter in either of two categories: a smaller-scale version where the object was to ignite an object from 5 ft (1.5 m) away, or the full-scale version, where the object was to ignite a replica trireme from 100 ft (30 m) away (as per the original myth). For the smaller-scale version, two finalists, the team of Kari Lukes and Jess Nelson, both from UCSB, and the team of Brenden Millstein (Harvard) and Stephen Marsh (Lawrence Berkeley National Laboratory) were chosen to compete against the MythBusters' own entry in the retest (which was disqualified when it was found that the MythBusters had not followed the contest rules they had set out themselves). Only one entrant (Mike Bushroe, a NASA space scientist) entered a full-scale contest; however, the winning entry was destroyed en route for the retest.
The MythBusters also invited a team from MIT, led by Professor David Wallace, who had independently verified that a ship could be lit from afar using an array of mirrors, to retest the myth with Archimedean-era technology instead of the modern technology used in their own experiment.
|An array of bronze mirrors can set a wooden ship on fire. (From Ancient Death Ray)||Re-Busted||The large-scale array simply took too long to light the ship on fire. In addition, the ship only ignited when it was stationary and positioned at less than half the distance described in the myth. The myth was plausible at a smaller scale, however. Flaming arrows were fired from a ballista at the ship, but to little effect. The most effective (and plausible with Archimedes-era technology) method of lighting the ship ablaze was through the use of Molotov cocktails.|
While it was shown extensively that it is, in fact, plausible that an array of mirrors (or a parabolic mirror) could set objects on fire, the MythBusters stood by their original Busted verdict because of many factors:
The MythBusters also addressed fans' criticisms that suggested they try to light the ships' sails instead of the body of the ship, and showed the sails diffused the light due to their composition and the wind blowing against them, thus could not be as easily set on fire compared to the body of the ship.
The myth would be re-visited in 2010 in the President's Challenge only to be re-busted.
Adam and Jamie took on a myth prevalent around football circles, made more prevalent during the time of prolific punter Ray Guy, whose kicks carried so much distance and had so much hangtime, some had suspected the footballs he used were filled with helium.
|A regulation NFL football will fly farther when filled with helium as opposed to compressed air at regulation pressure (13 psi or 90 kPa).||Busted||Under the same amount of impulse under the same atmospheric conditions, balls filled with helium showed no significant difference from balls filled with compressed air. Under the same impulse, both types of balls had the same initial velocity; since the helium-filled balls have a lower mass than the air-filled ones, the helium-filled balls have less inertia in flight: in fact, they may perform worse than air-filled balls over larger distances.|
The Build Team took on the bullet catch magic trick, and see whether it is possible to do the trick for real.
|It is possible to catch a fired bullet in one piece with one's teeth.||Busted||A pig's teeth are significantly stronger than a human's, and yet were shattered by an impulse test when a bullet, held by a pig head's teeth under the same pressure as an average human's maximum bite strength, was suddenly forced forward by a force equivalent to a speeding bullet. Furthermore, the reaction time needed to perfectly capture a bullet in one's teeth is too short and has too tight a tolerance for any human to succeed. Finally, when the bullet was captured perfectly, the velocity at which it traveled completely destroyed even a full metal jacket bullet: it is impossible to catch a bullet in the same state as it exited a gun, by solid mechanical means.|
The Build Team took on a piece of American folklore regarding Benjamin Franklin's discovery of lightning as electricity. The folklore description is not historically accurate (as mentioned by the Build Team), although it is a popular misconception.
|When Benjamin Franklin showed lightning to be electricity by flying a kite during a thunderstorm, could he have survived the shock?||Busted and Confirmed||The experiment itself worked perfectly as described, but the current produced by artificial lightning (which is a fraction of what a real lightning bolt would contain) was fatal. Based on this observation, the Build Team concluded Franklin could not possibly have survived a direct hit as the popular story of the experiment states. They also found the kite need not be directly struck by lightning for the experiment to work. Experiment: confirmed; story: busted.|
In this myth, Adam and Jamie tested some of the more prevalent myths based on flatulence. Throughout the myth, the MythBusters were careful to only use the scientific term 'flatus' as opposed to the more common 'fart', to prevent coming off as insensitive to the viewers (although 'fart' had been used and aired uncensored by the MythBusters before and since).
Flatulence can be induced by consuming...
|...beans.||Confirmed||While consuming a diet of beans for one day, Adam's rate of flatulence doubled.|
|...carbonated soft drinks.||Confirmed||While consuming only carbonated drinks for one day, Kari's rate of flatulence doubled.|
|...beef.||Busted||Jamie's rate of flatulence did not change after consuming a diet of beef for one day.|
|It is possible to flatuate so much, one can suffocate from the gas expelled.||Busted||The amount of potentially deadly gases found in an average flatus, such as carbon dioxide, is too low to cause its concentration to rise to fatal levels in a few hours, even in a small, airtight room. In fact, breathing causes the CO2 levels to rise much faster.|
|Lighting a match will burn the odorous gases in a flatus.||Busted||Lighting a match does not reduce the concentration of hydrogen sulfide and methyl mercaptan, the odorous gases commonly found in flatulence. The smell of a safety match being ignited instead masks the smell of methyl mercaptan when tested individually.|
Two additional myths were filmed but not aired as part of the broadcast episode. These have been shown in an outtakes reel at live appearances by the MythBusters.
|Pretty girls do not pass gas.||Busted||Wearing special undergarments fitted with a microphone and patched through a sound system and given a hydrogen sulfide meter, Kari was given the lead in this myth. Despite the meter malfunctioning and many hours without any sound broadcast over the speakers, Kari finally produced a flatus and busted the myth.
This myth was later shown as part of the MythBusters Mailbag special, aired on May 20, 2012. It was cited as Kari's most embarrassing moment on the show.
This is also referred to as "Flatus Burning."
|It is possible to ignite a flatus.||Confirmed|
Adam began by welding attachments to an ordinary chair to allow him an optimal position. Adam waited patiently for a flatus to surface. Using a standard lighter, the high-speed camera showed the flatus did indeed combust, confirming the myth. This myth was later shown as part of the MythBusters Top 25 Moments special, aired on June 16, 2010.
|A person can fly using a life raft filled with helium.||Busted||The amount of helium required to lift a person off the ground (or even the raft itself) is prohibitively immense, and such a raft of adequate size would be quite flimsy. In fact, the final test of the raft had to be aborted because of an unbalanced release of the ties, causing Adam to become entangled and destroying the raft in the process.|
|The ban on cell phones on aircraft is designed to force passengers to use the expensive in-flight phones.||Busted||Cell-phone signals, specifically those in the 800–900 MHz range, did interfere with unshielded cockpit instrumentation. Because older aircraft with unshielded wiring can be affected, because of the possible problems that may arise by having many airborne cell phones "seeing" multiple cell phone towers, and because of all the electronic systems in a modern airplane that would have to undergo lengthy and expensive certification, the MythBusters speculated that the FCC (by enforcement through the FAA) prohibits the use of cell phones while airborne to remain on the safe side, rather than the air companies asking for the ban to increase their revenue from in-flight phones. Such a prohibition was lifted in Europe.|
|Bullets fired into the air maintain their lethal capability when they eventually fall back down.||Busted, Plausible, and Confirmed||In the case of a bullet fired at sufficiently close to a vertical angle to result in a nonballistic trajectory, the bullet would tumble, lose its spin, and fall at a much slower speed due to terminal velocity, so is rendered less than lethal on impact (the Busted rating). However, if a bullet is fired at a lower angle allowing for a ballistic trajectory (a far more likely case), it will maintain its spin and will retain enough energy to be lethal on impact (the Plausible rating). Because of this potentiality, firing a gun into the air is illegal in most U.S. states, and even in the states where it is legal, it is not recommended by the police. Also, the MythBusters were able to identify two people who had been injured by falling bullets (fired from about 1 mi (1.6 km) away, hence at a lower angle), one of them fatally (the Confirmed rating). This is the only myth to receive all three ratings at the same time.|
|...remove poison oak.||Busted||For some reason, although most of the MythBusters were allergic to poison oak when they were young (especially Kari, who was exempted from the test because she had once had a dangerous reaction), it did not affect anyone but John the Researcher. The vodka still gave no results.|
|...painlessly remove plastic bandages.||Plausible||Both a control and vodka-soaked bandage were quickly removed from hair-covered legs and, while not painless, the vodka-soaked bandage came off less painfully and removed less hair than the control.|
|...be used as an improvised ice pack when mixed with water in a sealed plastic bag. (This myth was not seen in the version aired in the US.)||Confirmed||After the mixture was put inside the refrigerator overnight, the vodka (which has a lower freezing point than water) prevented the water from freezing, making the mixture cold and malleable. When tested against a commercial ice pack for twenty minutes, the mixture worked just as well, although the commercial ice pack was slightly better by about half a degree Celsius or one degree Fahrenheit (about 18.3 °F or −7.6 °C for the commercial ice pack against 19.4 °F or −7.0 °C in the vodka/water mixture). Tory even joked after the test that the mixture could make a good slushie to drink after use.|
|...be turned into high-quality vodka through charcoal filtration.||Busted||Through a double-blind taste test, the cheap vodka seemed to taste better with every subsequent filtration, although the top-shelf vodka beat them all. However, a chemical analysis showed no actual difference between the filtered and unfiltered cheap vodka.|
This was the fourth episode in which myths were retested (counting the Archimedes Death Ray revisit).
|A hybrid rocket can be propelled with salami. (From Confederate Rocket)||Confirmed||Salami, like the paraffin used in the first test, was able to propel the rocket, although it tended to explode instead of providing even thrust.|
At the insistence of viewers, the team retested the popular arrow-splitting myth seen in the film The Adventures of Robin Hood.
|An arrow can be split in half through a direct hit in the tail by another arrow. (From Splitting an Arrow)||Re-Busted||Even after multiple direct hits on a solid wood arrow with the bone nock removed with a professional archer, a tail-to-tip split could not be achieved. It took an arrow made of hollow bamboo to create the splitting effect seen in the movie, because the second arrow will follow the grain of the first, normal arrow, which will lead to the side before it makes it to the end. Also their tests revealed that an arrow fired from a traditional bow wobbles in the air enough that it will not hit the end of the arrow straight.|
It has already been shown that, in some cases, bullets become non-lethal when fired into water, but what happens when the whole gun is fired under water?
|A modern firearm can be fired if completely submerged in water. (From Bulletproof Water)||Confirmed||All of the firearms (a 9mm, a .357, a 12-gauge shotgun, and a .30-06) could be discharged under water, but the bullets lose velocity rapidly and are rendered less than lethal beyond a meter. (The entire gun had to be completely submerged in water—all pockets of air must be removed—to prevent a possible explosion when fired.) Furthermore, the break-barrel shotgun (a relatively old design) destroyed itself when fired under water. Finally, the water pressure might cause the spent cartridge casing to fail to leave the chamber and effectively reduce the gun to a one-shot deal. Obviously, revolvers would not have this problem, as they do not eject their spent casings after each shot.|
|A small room can be quickly painted by detonating a stick of dynamite in a bucket of paint.||Busted||A stick of dynamite in a bucket of paint cannot distribute the paint evenly enough to fully paint the room; only 40% of the room (around the bottom and part of the ceiling) received paint, and the room took some shrapnel damage (even from a plastic bucket). Furthermore, Adam's and Jamie's customized contraptions, designed to help distribute the paint more evenly, failed to produce any successful results or an intact room.|
Remote, non-consensual mind control can be achieved by...
|...a psionic helmet kit, ordered off the internet.||Busted||The test failed to produce any effects. Tory wore the helmet for two tests. The first was an attempt at a local coffee shop to give his order to the clerk without telling her, which failed (although the women behind him claimed to receive the message he was trying to broadcast). In the second attempt, he attempted to make Jamie remove his trademark beret, with no effect, while Jamie was filming the wrap-up for Facts About Flatulence. (Tory, in fact, is visible in the rear of the shot during that episode wearing the helmet.)|
|...pulsed air.||Busted||The test failed to produce any effects.|
|...a spinning magnet.||Plausible||While it is plausible that some sort of "mind influence" (determined by looking at EEG recordings) was achieved, no actual predictable control of the mind's state occurred. Also, the magnet may have affected the EEG machine's readings.|
|...subliminal sound.||Busted||The test failed to produce any effects.|
|...remote hypnosis.||Partially Plausible||Enough pre-existing scientific evidence exists regarding hypnosis for the Build Team to call the myth plausible, and their EEG readings backed up that evidence. However, a later myth busts the possibility that one could coerce another person into doing something against his will through hypnosis, so while someone's brainwaves can be influenced through hypnosis, true "mind control" cannot be achieved with it.|
This myth came from New Zealand in the early 1930s, where an epidemic of exploding pants had rampaged, injuring and even killing farmers. The culprit was a then-unfamiliar chemical substance that farmers began using in large quantities at the time.
|Under the right conditions, farm chemicals can cause a pair of trousers to combust if they are spilt on and subjected to normal wear and abuse.||Confirmed||The Build Team tried to ignite cotton denim pant swatches soaked in fertilizer, gun cotton solution, black powder, and the herbicide sodium chlorate using an open flame, radiant heat source, friction, and impact, but only the herbicide could ignite with sufficient energy under the above conditions (except for friction), and it was particularly reactive to impact. In a full-scale experiment using Buster, paramedics on-hand stated that Buster would most likely survive the blast with only some burns. Research confirms the herbicide as the culprit, as an accidental infestation of ragwort in the country caused a dramatic increase in herbicide use. Despite the fact that it was technically not a true explosion (as there was no rapid air compression typical of an explosion), it was agreed that the rapid flash ignition of the pants was quick and energetic enough to be deemed an "explosion" by a layman, rendering the myth confirmed. After determining this, Frank Doyle and the MythBusters painted Buster's pants with classified "Silver" explosive and the resulting blast completely destroyed him, throwing pieces of his body in all directions.|
The "Great Gas Conspiracy" mentioned in the myth is the conspiracy theory that gasoline companies are secretly in league with the car manufacturers to produce fuel-inefficient vehicles, to fatten their profits and split the difference. The myths tested were ways found on the Internet that one can supposedly beat this conglomerate and get cheap, easy, and spectacularly improved fuel efficiency for cars. The cars were a Toyota Camry and an Oldsmobile Toronado.
Theories tested to see if cheap fuel efficiency can be achieved with...
|...carburetor magnets.||Busted||No change to fuel efficiency.|
|...acetone mixed with the gasoline.||Busted||The acetone was less fuel efficient.|
|..."miracle carburetor" supposed to get 300 miles per gallon.||Busted||Far less fuel efficient.|
|..."water fuel cell".||Busted||The cell did not work with the car, and while the car did start unmodified when pure hydrogen was introduced, the hydrogen was also violently ignited soon afterwards, making it an unlikely, dangerous, and expensive alternative.|
|...used cooking oil, rather than regular fuel.||Confirmed||Although there's no word on damage to the engine from using used cooking oil, a Mercedes-Benz diesel-fueled car did run on it. However, the MythBusters speculate that once this alternative fuel achieves a significant interest level among the public, used cooking oil will be hoarded as a marketable commodity. The used cooking oil also did not quite fit the requirement of improved fuel efficiency, as it yielded approximately 10% less distance for an equivalent amount of diesel. (see biodiesel and straight vegetable oil)|
The MythBusters tested the validity of some Hollywood heist scenes, using a purpose-built "assault course" with Grant operating the security system as mission controller, while two "crack teams" (Adam and Jamie, plus Tory and Kari) attempted alternate myths.
Though present in a number of movies, the myth came primarily from the movie Firetrap, in which Max Hopper (Dean Cain) scales a duct silently using magnets. Adam and Jamie were tasked with the entry phase – scaling a 20-foot air duct stealthily. After each had devised his own system, they tested whether a person can surreptitiously scale an air duct by using a system of...
|...magnets.||Busted||Jamie's "supermagnets" (ten 500-pound (230 kg) strength ones) could hold his weight and allowed him to make it to the top of the duct, but they caused far too much noise on the way up to allow for a stealthy entrance.|
|...suction cups.||Busted||Adam's suction cups were able to hold his weight as well and were relatively much quieter than Jamie's magnets, but the climb was still clearly audible. Further, the mechanisms Adam used to control the vacuums often failed, which caused him to slip and fall down the vent, blowing his cover. He did, however, make it to the top of the vent, once he perfected the method of operating the device in sequence to his steps up the vent. Finally, breaking through the grate of the air duct at the end was much too noisy, also blowing his cover.|
Before Grant started the myth, he stated that he found that the highly visible, brightly colored lights beams seen in movies, do not exist in the real world, as not only would it defeat the purpose of making the laser system hard to get around, but real light moves far too quickly to be seen by the naked eye, thereby making such laser systems impossible to create in the first place. In its place, he fashioned a makeshift system using laser pointers that worked on the same principle (breaking the beam sets off the alarm.)
Each part of the myth came from the movie Entrapment – specifically, the scene where Gin Baker (Catherine Zeta-Jones) and Mac MacDougal (Sean Connery) infiltrate Bedford Palace to steal a priceless mask. Kari and Tory took this on as their first challenge and tested whether a person can successfully navigate a system of laser beam detectors by...
|...blowing cosmetic powder across the beams to identify their position, as Gin did with the final beam.||Busted||While visible beams can be seen, they are only detectable when the powder is airborne, which is not very long. Also, as Kari found, blowing too much powder can cause enough of the beam to break and set off the alarm. Furthermore, most laser systems use invisible infrared laser trip beams.|
|...using night vision goggles. Inspired by Mac's use of a night vision camera to navigate Gin.||Busted||None of the beams are visible through the goggles - Tory was only able to see the points where the beams were hitting. He said that the goggles actually made it harder to get through the lasers.|
|...pointing another laser at the photodetector – another technique that Gin used once.||Busted||While the technique is workable enough with visible-beam systems, the fact that infrared beams cannot be readily detected or traced makes locating the relevant photocells too difficult in a real-world situation.|
After getting through the visible lasers, Kari and Tory faced the real-world equivalent: infrared photo-beam detectors. They tested the following methods:
|...the Entrapment techniques (cosmetic powder, night vision goggles, or both.)||Busted||Neither Kari's makeup nor Tory's night vision goggles helped them see the infrared beams, and while a combination of the two allowed Tory to catch a momentary glimpse of the infrared beams, Kari still found that she had a problem in that it was still possible to break the beam by blowing too much powder forward.|
|...using an optical doorway.||Busted||In a scene not shown in some versions of the episode, Kari built an apparatus that deflected the beams from mirror to mirror until it reached the receptor while creating a doorway that she and Tory could walk through. However, the device was massive, and just sticking it in was enough to set off the alarm. When Grant temporarily disabled the alarm to give them time to set it up, it did work, but it was deemed busted due to its impracticality.|
To access the jewelry room, Adam and Jamie tested whether glass doors can be breached silently (i.e. without setting off a sonar alarm trained to detect smashing). This was inspired by films often featuring scenes where cat burglars cut holes in glass and remove them with suction cups. They tested the following techniques in an hour-long practice session and during the test itself...
|...gently cutting the glass and removing it with a suction cup.||Busted||The suction cup could not remove the glass.|
|...thermal shock (extreme hot and then freezing cold to fracture glass along a circular groove.)||Busted||When Jamie tried it during a practice run, the method failed catastrophically, so it was not used in the actual test.|
|...tapping a hole in the glass.||Busted||Although it did work, it was far too noisy and set off the alarm during the test.|
|...drilling a hole.||Partially Busted||The drilling caused some noise, but not enough to trip a sonic alarm. It did, however, cause the entire glass panel to break, but because it was tempered and laminated, the glass held together. Jamie then used pliers to pick out the pieces until an arm-sized hole could open up, allowing access to the doorknob on the other side, but it was a near impossible task to do consistently.|
This myth also came from Entrapment and is the final act of the Bedford Palace mask heist. Tory and Kari faced this as their final challenge, attempting to retrieve a golden Buster idol while testing whether person can successfully fool a pressure sensor under a glass case by...
|...squeezing in a knife between the glass and sensor and using a piece of gum to hold the sensor in its original position, as Gin did.||Busted||The sensor is extremely sensitive. Even the slight lifting of the case needed to insert the knife can set it off, and it took three attempts just to get the knife in. Also, the freshly chewed gum is too pliable to keep the sensor held down once the knife is removed.|
|...squeezing in a knife between the glass and sensor and using duct tape to hold it in place.||Plausible||This was Plan B in case the movie myth was busted, as Tory reasoned that they would bring tape if they were in a heist. If one can get the knife in without setting it off, the knife can then be held in place with tape to keep the sensor depressed.|
|...overloading the pressure sensor.||Plausible||In a segment not shown in some versions of the episode, right before the safecracking, Adam set off a pressure sensor that Grant installed on the floor right in front of the safe. He successfully overloaded it, though, turning the pedestal that had held the Buster idol on its side and putting it on the sensor to overload it.|
As their final challenge, Adam and Jamie were tasked with cracking a safe that turned out to contain a golden jeweled scepter. Adam took the lead and tested whether a safe can be quickly cracked by...
|...using a stethoscope.||Busted||Modern safes are designed with this old technique in mind, and the tumblers proved too quiet to be heard even with amplification.|
|...drilling a hole and visually causing the tumblers to fall into place.||Plausible||After prying off the safe knob, with help from a borescope and a length of piano wire, Adam managed to crack the safe, but it would take time that may not be available to a surreptitious safecracker (for Adam, 45 minutes), especially given the fact that the safe for the test was rated to be crackable by a professional safecracker in only 5 minutes—although most safecrackers are not normally required to be quiet in doing so.|
In a final twist, Grant and Tory challenged Adam to scale a 23-story building using his suction cups as a cat burglar might in order to get to a helicopter on the roof.
|A suction cup system can be used to scale a (23-story) skyscraper.||Plausible||The concept worked (see the Air Duct Climb section) but Adam did not have the stamina to scale the entire building. Making the climb would be highly visible and requires significant physical training.|
A popular saying states that sugary cereal is less nutritious than its box.
|A cereal box can have more nutritional value than the cereal.||Busted||All tests showed that cereal has superior values of calories, fats, sugars, and proteins compared to cardboard. Furthermore, chemicals within the cardboard may be toxic.|
|Archimedes was able to build a powerful steam cannon, using technology available at the time.||Busted||A flash-boil-powered cannon, built even with modern materials and techniques, was barely able to push a projectile out of the barrel. A more modern pre-boiled, valve-triggered system, like those used in aircraft catapults, was able to project a cannonball a considerable distance, and required far less pressure than the MythBusters had originally projected. Also see Holman Projector which worked on a similar principle.|
This is also referred to as "Which has the whitest teeth." This myth was less a challenge than an inside joke. The MythBusters received many emails from fans complaining about Adam's brown teeth. It was not aired in the US. However, on the Discovery Europe version, it is included in the episode.
|Of all the MythBusters, Adam is the one with the brownest teeth.||Busted, then Confirmed||Jamie, Adam, Tory, and Grant all had their teeth checked by Kari. At first Jamie was the one with the brownest teeth, not Adam. However, after hearing the news, he had his teeth bleached to make them white again. After this, Adam did have the brownest teeth. The overall result, from best to worst: Grant, Tory, Adam, and finally Jamie (before his bleaching).|
Whirlpools are an ancient maritime fear. According to the myth, a tidal whirlpool can sink...
|...a container ship||Busted||For this to happen, the whirlpool would have to be significantly stronger than any maelstrom ever recorded.|
|...a fishing trawler||Busted||For this to happen, the whirlpool would have to be significantly stronger than any maelstrom ever recorded.|
|...a person||Plausible||A whirlpool can generate a vortex large enough to pull down a swimmer and, especially if combined with the effects of dizziness and disorientation (which caused Adam to vomit after mere seconds), induce drowning. The MythBusters only tested according to the most powerful maelstrom ever recorded, and did not determine the minimum size needed to submerge a swimmer.|
A fan claims that he saw a car capsize when a snowplow passed by in the opposite direction at high speed.
|A snowplow passing by at high speed can displace enough air on one side to flip over a passing car.||Busted||Even a worst-case scenario—an unusually large plow passing by a light, top-heavy sports utility vehicle at highway speed – could not generate the air pressure needed to cause the SUV to even visibly tip. A semi driving at highway speeds only generates about 1/6 of the air pressure needed to make this myth plausible.|
This is the first segment not to be assigned a "Busted", "Plausible" or "Confirmed" rating, as there was no myth to be proved or disproved. Adam and Jamie did the tests simply to dissect the process and determine what actually makes a so-called Diet Coke and Mentos eruption, such as the ones seen on Kari's FHM shoot and on EepyBird.com. However, they did compare their results to the many differing theories given by experts as to how the geyser works, "busting" all of them. (None of the theories had the full list of contributing factors for the geyser, only partial explanations.)
The MythBusters also set a new record for the cola geyser at just over 30 ft (9.1 m) by using a nozzle, beating the previous record of 18 ft (5.5 m), set by the person who popularized the phenomenon, Steve Spangler. They extended the geyser to 34 ft (10 m) by using rock salt, which is more porous and hence provides even more nucleation sites per area than Mentos.
In this episode, Adam and Jamie also created homemade pyrotechnics using water, liquid soap, and methane, and smoke bombs from saltpeter and sugar; demonstrated a way to blow the canister off a stack of Pringles chips by using hydrogen gas, leaving the chips intact; and assembled a dry ice bomb. Adam also implies that more improvised explosives may be tested for a future episode. Despite the "do not try this at home" disclaimers, the MythBusters concluded that Diet Coke and Mentos geysers are safe enough for people to try, even for children (with the exception of getting in trouble by their parents).
|Why does dropping Mentos into a bottle of Diet Coke create a geyser effect?||Mostly because the (uncolored/unglazed version of) Mentos provides nucleation sites for the dissolved carbon dioxide in the Diet Coke to escape as a gas. Other active ingredients in the cascade-effect reaction include aspartame (artificial sweetener), potassium benzoate (preservative), and caffeine in the Diet Coke; and gum arabic and gelatin in the Mentos. The ingredients seem to have a perfect compatibility with each other and, when mixed and added to the nucleation, creates a chemical reaction that forces the soda to release all of its dissolved carbon dioxide at once, thus causing a more violent eruption than carbonated water alone.|
|A stamp placed on the rotor of a helicopter can unbalance the spinning rotors enough to cause it to crash.||Busted||A stamp in a controlled scale test did not cause any changes to the helicopter rotor's rotation. The MythBusters immediately ramped up the test to the scale of 8,000 stamps, which destroyed the scale model helicopter. The full-sized test also produced the same results, as the stamp did not cause a real helicopter to crash, and according to the pilot, did not cause any significant change in the way the helicopter flew. A stamp placed on the tail rotor also did not cause any noticeable change.|
|One can design an automobile sound system such that the bass can quickly shatter all the windows of the automobile.||Busted||While the large, diesel engine-powered subwoofer that Jamie and Adam built into a Mercedes-Benz 240D produced sound at 161 dBSPL at 16 Hz (a level comparable to those found in cars specially designed for loudness competitions), it caused the sunroof of the car to jar loose, allowing for the pressure of the sound waves to escape. Because of this leakage, not to mention the fact that the forces behind the oscillation caused the woofer to break apart, the speaker system could not possibly create the intensity needed to cause all the windows to explode as the myth stated. A best-case scenario would involve only one window failing, thus creating a path for the pressure to escape.|
A spinoff myth was tested in More Myths Revisited
|A car will achieve a smoother ride on a rough outback road by being driven faster.||Confirmed||As far as driving on non-washboard roads, there was no solid conclusion due to a conflict of data. However, when they tested a "washboard" road, the Build Team were able to confirm the theory that driving at a higher speed will indeed cause the body of the car to float over the ridges: the wheels of a car oscillated wildly, but the car suspension allowed for a relatively smoother ride at high speed.|
As opposed to the earlier Crimes and Myth-Demeanors, which focused on security systems as seen in movies, the MythBusters attempted to break real-world security systems, which were all installed in the original assault course.
Fingerprint readers take a sample of a fingerprint and match it with an approved-person database. The particular door-mounted scanner tested optically samples the fingerprint, and had some extra "liveness-sensing" features that supposedly looks for pulse, body heat, and sweat (though, in the end, the door-scanner ended up being fooled much easier than the low-tech fingerprint scanner on Jamie's laptop).
The process was twofold – first, obtaining the thumbprint for the lock (which Kari did by tricking Grant into copying a stack of CDs, thus giving them a copy of the master print) and then devising a method of successfully transcribing the fingerprint to the point that it could be used to bypass the lock. Adam and Jamie used various techniques before finding a technique involving copper-coated circuit boards, acetate, acid washing, and manually amplifying the lines in the fingerprint to their original quality.
After that, the two of them transcribed Grant's thumbprint onto various mediums and then tested whether the biometric fingerprint lock could be cracked by...
|...a copy of an approved fingerprint etched in latex.||Confirmed||Adam first planted the latex on his own thumb to give it warmth and pulse and then found that licking the latex sample (to simulate sweat) was enough to fool the scanner. This allegedly marked the very first time that particular lock had been broken.|
|...a ballistics gel copy of an approved fingerprint.||Confirmed||Jamie was also able to fool the sensor after adding some moisture to the ballistics gel print.|
|...a paper copy of an approved fingerprint.||Confirmed||Licking the paper sample (to simulate sweat) was enough to fool the scanner.|
Thermographic cameras note any changes in the temperature gradient within its field of view (as seen in the 1992 film Sneakers). Kari, Tory and Grant tested whether a thermal motion sensor can be fooled by...
|...cooling the body down using a CO2 fire extinguisher||Busted||Not only was the sensor not fooled, but using a fire extinguisher on a person is dangerous.|
|...a neoprene diving suit.||Busted||The neoprene suit did insulate Tory's body heat from his surroundings – until the suit itself warmed up.|
|...being covered in mud. Inspired by a technique used by Dutch Schaefer (Arnold Schwarzenegger) to fool Predator thermal sensors.||Busted||Like the neoprene suit, it only worked until the mud warmed up from body heat. Also, Tory left behind mud tracks while attempting this, making him easier to track.|
|...heating the room to body temperature.||Busted||Heating the room from the ceiling immediately set off the sensor, while heating the room from the ground did not. However, the sensor was still sensitive enough to detect the difference between human body temperature and the ambient temperature. They also attempted piping the heat in from below and then having Grant strip down to his boxers (as close to naked as he dared in an attempt to emit exactly 98.6 degrees), but that was also unsuccessful.|
|...wearing a highly insulated fire proximity suit.||Confirmed||In a scene not shown in some versions of the episode, they found that the suit blocked the body heat, preventing the sensor from seeing the wearer. However, a small breach in the suit around Tory's buttocks area triggered the sensor when pointed towards it. Despite that, though, he found he was able to beat the thermal camera by entering the room backwards.|
|...placing glass between the intruder and the sensor.||Confirmed||Glass blocks out the longer wavelength infrared light used by thermal imaging systems. Kari and Grant were successfully able to hang a pane over the camera using a clamp and drop right into the room.|
|...wearing thick-padded clothing||Busted||To test this, Kari made a Big Bird-like costume-cum-stealth suit out of a thick yellow rug, but the sensor was still able to pick up her movement.|
|...wearing a suit made of fiberglass||Busted||Kari made a second suit made of the said material, but the alarm went off the instant she set foot in the room.|
|...holding a bedsheet in front of oneself.||Confirmed||The bedsheet absorbed enough of the ultrasonic waves to mitigate any return signals.|
|...moving extremely slowly.||Confirmed||Although it took Kari 20 minutes to cross a relatively short hallway, she moved slowly enough to stay below the detector's sampling threshold.|
|A thief can drill into a safe with a thermal lance, fill the safe with water, and detonate an explosive inside without damaging the items inside or prematurely activating the glass relocker.||Plausible||Drilling into a safe using thermal rods takes far longer than the myth states. Also, the heat from the thermal rods completely destroyed the items inside. Secondly, the safe was not watertight and had to be sealed from the inside to completely fill it with water. Finally, though the explosion successfully dislodged the safe door, none of the items inside remained intact. It was deemed plausible from historical precedent and police reports, though the MythBusters themselves could not replicate any of the conditions. The myth was also tested by the BBC show Hollywood Science, which was able to replicate the scene using the same type of safe used in The Score.|
|Tesla's oscillator: Nikola Tesla invented a small steam-powered machine that, when attached to an object or building and tuned to vibrate at a certain frequency, can cause an earthquake-like effect on the object to which it is attached.||Busted||The MythBusters built several variations of Tesla's machine using modified jackhammers, as well as a specially designed computer-controlled electromechanical linear actuator provided by Grant. Small-scale tests on metal bars produced mixed results, with the modified tools performing poorly, while the more finely tunable actuator produced significant vibrations in the bar. A scale-model test with a model of Tesla's lab and miniature motor failed to produce any noticeable result. Finally, a full-scale test was attempted: the MythBusters attached the resonator to the side of the 1927 span of the Carquinez Bridge, a large truss bridge of a type today designed to withstand such vibrations, to see whether the entire bridge would be shaken. The resonator could be tuned to the bridge's resonant frequency; it did produce a vibration, noticeable "hundreds of feet away", like "a big semitrailer truck cruising by", but not remotely of earthquake strength. The MythBusters declared the myth busted.|
Kari, Tory and Grant began by examining the news story that 24-year-old Philip Quinn had been killed two years beforehand in his trailer home in Kent, Washington after he heated a lava lamp on his stove, only for it to blow up and send a glass shard into his chest. This earned them the moniker of "MSI: Myth Scene Investigation", an homage to CSI. They eventually tested whether the following can potentially blow up with lethal consequences if heated on a stove by heating the material in question on a stove and placing a ballistic gel torso with an actual human ribcage and a fake heart near the stove so that they could examine potential injuries:
|...a lava lamp||Confirmed||All lava lamp tests produced violent reactions, with the reactions differing depending on the lamp's design:
|...a can of beans||Confirmed||The cans of beans tested exploded with force proportional to the size of the can. Larger cans explode more violently than smaller cans, especially since large cans do not have a weakened pop-open top, but the Build Team concluded that any can of beans on a stove is potentially lethal.|
|...a can of potted meat (such as Spam.)||Busted||Though the can of potted meat exploded rather violently, the explosion did not have enough force to be deemed lethal.|
|...a large glass jug of milk||Plausible||The jar of milk exploded violently, though not with a large amount of force. The Build Team concluded that an exploding jar of milk could be lethal if a person happened to be standing over it.|
|A piece of straw can penetrate all the way through a palm tree if propelled by hurricane-force winds.||Busted||Propelling a piece of straw at a palm tree at a distance of 50 cm (20 in) at 320 mph (510 km/h) (the world record for recorded wind speed at ground level), the straw only managed to penetrate the tree a quarter of an inch. Even firing at the tree while it was bent (to increase the size of the pores in the surface of the tree) at point blank range added no additional distance into the tree. A piece of reed was tested as the sturdiest organic object that might be mistaken for a piece of straw. At both ranges, the reed only managed to go about two inches into the tree. Additionally, Jamie tried a piece of piano wire, and at 50 cm, it flew not only through the tree, but also through a sheet of plywood on the wall behind it, partially embedding itself into the concrete wall.|
|Wind alone can blow the feathers off a chicken.||Busted||Even wind speeds faster than those ever recorded could not remove any of the feathers of a tethered chicken. The whole bird would more likely be blown away completely.|
|Polygraph tests indicate all living things share some form of interconnected consciousness.||Busted||Tests were done by connecting plants to a polygraph's galvanometer, and then employing actual and imagined harm upon the plants or upon others in the plant's vicinity. The galvanometer showed some spurious readings (showing some kind of reaction about one-third of the time), so a much more accurate EEG machine was used. When Grant and Tory used a machine that dropped eggs randomly into boiling water, the plant had no reaction. Additionally, Tory's leukocytes had no reaction when Kari shocked him with a stungun.|
Adam, Jamie, Buster, and the Build Team are watching movie myths they have done in the past, and decide to dedicate a whole episode to them. This episode is a two-hour special.
|The Dukes of Hazzard: A car can jump a significant distance using a pile of soil as a ramp and land with minimal damage or loss of momentum.||Busted||The car managed to jump 172 ft (52 m), 3 ft (0.91 m) short of the estimated span of the gorge jumped in the movie. However, the car crashed nose-down and the front and engine were crumpled, busting the myth (and the car). It is somewhat widely known that stunt cars are often heavily damaged by bigger jumps and must subsequently be scrapped (see The General Lee).|
|Big Trouble in Little China: A lock can be broken by shooting it with handguns.||Busted||The 9-mm pistol and the .357 Magnum failed to open either the padlocks or the deadbolts.|
|Various movies: A lock can be broken by shooting it with shotgun slugs or high-powered rifle ammunition.||Plausible||Both types of ammunition were able to disable the locks by completely obliterating them. However, the MythBusters note that this lock-busting method would be very dangerous in real life due to ricochet or spalling. Because of this hazard, military and SWAT units use a special shotgun cartridge called a breaching round to break through doors.|
|Goldfinger or Austin Powers in Goldmember: A car can be equipped with a discreet ejector seat.||Plausible||A pneumatic ejector seat fitted into a boxy Toyota car seemed to fool most of the people who inspected it, and the seat successfully launched a test dummy out of the car. However, the design of the car plays a huge role in concealability, which is why Jamie and Adam opted for a roomier, boxier car rather than one of the flashy and sleek sports cars often seen in spy movies. Sports cars have windshields that extend partially over the front seats, making it difficult for an ejector seat to properly launch without hitting the frame.|
|Indiana Jones and the Temple of Doom: A person can fall through layers of awnings and survive.||Plausible||Buster was broken into pieces during the fall, but "survived" his fall (according to the shock sensors) with less-than-lethal (but still serious) "injuries". Tory then demonstrated the movie method of using pre-cut awnings and safety wires (after Adam was prevented by the show's insurance from doing it himself).|
|Underworld: One can escape through a floor by shooting through it in a circular pattern.||Busted||A fully automatic MP5 failed to break through the support beams underneath the floor in any reasonable amount of time, even with the assistance of a 12-gauge shotgun. Tory also had to fire all of his 360 rounds of ammunition to even come close to breaking through. Finally, due to the close proximity of the shots to the shooter, flying debris and the possibility of ricochets makes this method extremely dangerous.|
|The Count of Monte Cristo: A sword can cut off the blade of another sword.||Busted||The team tested impacts between various types of swords. A genuine Japanese-constructed katana sliced through a replica stainless-steel sword, and also broke a genuine sword through stress fracturing. The katana bent a rapier until it snapped, but did not cut through the blade. When a Claymore struck the katana, the katana flexed but did not break. A Viking sword then severely nicked the claymore. In the end, though some swords did break, none of them were actually 'cut' by the impacting sword.|
A spinoff myth was tested in More Myths Revisited.
|Unofficial Myth: The MythBusters really know how to ruin a movie.||Confirmed||Tory storms out at the end of the special and says, "You guys 'really' know how to ruin a movie", to which Adam replies, "That's confirmed."|
|If a cable snaps, it can cut a person in two (as seen in the movie Ghost Ship).||Busted||A 5⁄8-inch (1.59 cm) cable at 30,000 pounds-force (130,000 N) of tension was unable to cut a pig in two (or even cut into it), but did cause potentially lethal injuries. The MythBusters took the test even further by adding a smaller cable at the end of larger one to create a "whip" effect, and even looped a cable around the pig itself. None of these methods could cut the pig by the pretensioned cable's inertia alone. The pig was cut in half only when Adam tied a cable around it before tightening the cable. Also, after making inquiries with almost every safety organization imaginable, the MythBusters were unable to find any concrete evidence of a person being cut in half by a snapped cable.|
|Sounds can be recovered from old pottery, called archaeoacoustics. (Based on The X-Files episode "Hollywood A.D.")||Busted||The MythBusters were unable to recover any recognizable sound from the pot using a record player with a glass needle (to prevent scratching the clay). Even with professional audio enhancement and the most advanced sound systems available, they were unable to recover any discernible sounds from the straw-made grooves on the pots.|
A compressed air cylinder can...
|...blast itself through a concrete wall.||Confirmed||Once the MythBusters constructed a launch tube and perfected shearing off the cylinder's valve, the cylinder shot entirely through their constructed cinder block wall and damaged the solid concrete wall behind it. The MythBusters were also aware of recorded instances of such a thing happening.|
|...power a speedboat.||Busted||The two cylinders could only propel the modified speedboat 120 ft (37 m) at a maximum of 5 kn (9.3 km/h; 5.8 mph). A second attempt resulted in the boat barely making half the distance, and barely registering any speed at all.|
|An engine can run on gunpowder alone.||Busted||The team (incorrectly) concluded that gunpowder has a greater energy density than gasoline and proceed to test three historical designs (by Huygens, Cayley and Paine) for gunpowder engines, none of which worked for more than one cycle; the team could not find a practical or reliable way to feed the gunpowder into the engines without having them backfire and ignite all the powder, most likely because black powder is not a liquid and therefore is not transported as easily; also, gunpowder cannot be ignited while mixed in with liquid (even flammable lubricating oil), so it must be dry for the engine to work. They were also unable to convert a modern lawnmower engine to run on gunpowder, even with gunpowder inserted directly into the ignition chamber.|
This was the fifth episode where myths from previous episodes were revisited.
|A sword can cut a machine gun in two (spinoff of Sword vs. Sword).||Busted||The team heated the barrel from a .30-caliber Browning machine gun until it was red hot and struck it with the sword machine, which only resulted in a small gouge in the barrel even though the barrel's outer heat-dissipating shroud had been removed and the machine was swinging the sword with power that significantly exceeded a normal human's capabilities. The team then rapidly heated and cooled the barrel to make it more brittle, but when hit by the sword again, it shattered instead of being cut. Finally, the team tried to cut a thinner Thompson submachine gun barrel, but the sword only bent it.|
|Bracing a windshield can keep it from shattering (spinoff of Rough Road Driving).||Busted||Bracing a window with a hand was unsuccessful in preventing a window from being shattered by a rock or a fired BB.|
This marked the first time a Confirmed myth was disputed. In this case, the claim was that the rocket launched not due to the two-part hybrid reaction, but simply due to the release of the pressurized nitrous oxide.
|A Hybrid Rocket can use salami as fuel. (from Salami Rocket).||Re-Confirmed||Using salami as a rocket fuel can create high amounts of thrust with the right nozzle. Readings from the force gauge proved that salami did in fact generate much more thrust than just the released nitrous oxide alone, though they do admit that the nitrous oxide output alone could have launched the rocket, as may have been the case with the original launch.|
|It is more fuel efficient to drive a pickup truck with its tailgate down, rather than up (from Tailgate Up vs. Tailgate Down).||Re-Busted||Using a calibrated fuel flow gauge, Adam and Jamie first re-busted the tailgate up vs. down myth, then went on to test various other truck configurations (hard top, mesh tailgate, no tailgate).|
|A plastic mesh tailgate provides superior fuel efficiency compared to the standard metal tailgate.||Confirmed||Again using a calibrated fuel flow gauge, Adam and Jamie proved that the mesh was the most efficient way to configure a pickup truck. The fans stated that the truck mesh was the worst tailgate to use, which the MythBusters proved wrong.|
The MythBusters tested the following myths concerning standard disposable butane lighters.
|A lighter can explode when placed under a welding tool.||Confirmed||The heat generated from the welding tool was hot enough to cause the plastic lighter to melt and release its fuel which ignited, causing a small explosion.|
|A lighter can explode when put in a laundry dryer||Busted||A lighter was left in a running laundry dryer but suffered no significant damage and therefore did not explode.|
|A lighter can explode when hit with a golf club.||Partly Confirmed||Hitting a lighter with a golf club did not make the lighter explode, but when the MythBusters decided to hit the lighter while it was lit, it exploded rather violently.|
|A lighter can explode on a car dashboard.||Busted||The lighter was put in a toaster oven to simulate the maximum temperature that the interior of a car can reach, around 180 °F (82 °C). There was no reaction for several hours, and the lighter finally exploded when the MythBusters ramped the temperature up to over 350 °F (177 °C), well above any temperature that can be expected in the interior of a car.|
|A single lighter can be lethal if it explodes.||Busted||The MythBusters placed a lighter in a pair of jeans on a pig carcass used as a human stand-in, and put it under a welding tool. The sparks and heat from the tool managed to set the pants on fire and burn the flesh, but failed to ignite the lighter.|
|Five hundred lighters packed inside a car can explode with lethal force.||Plausible||The MythBusters placed 500 lighters in a car and slowly heated it up. One by one, lighters began to rupture and release gas fumes. When the MythBusters finally triggered an igniter, the gas fumes exploded, blowing out all of the windows and setting the car on fire. The myth was deemed possible as long as a suitable ignition source is present.|
|...drop a coin and fire his pistol five times before it hits the ground.||Busted||Using replicas of actual Wild West pistols, Grant, Kari, and Tory attempted the stunt themselves. However, Grant and Kari were unable to clear the pistols from their holsters in time and Tory was only able to get off one shot. Grant then built a device which showed that the pistols consistently jammed when the MythBusters tried to fire them so quickly. The MythBusters finally turned to a professional gunslinger, Larry Hamby, but he could only fire three shots, and he stated that firing five in that period of time would be "extremely difficult". With no results, the myth was busted.|
|...shoot a hole through a silver dollar.||Busted||The MythBusters used actual period silver dollars for the test. A professional gunslinger proved that 'hitting' the coin was possible (if thrown correctly, on the first try) by piercing a lead coin. Both the Peacemaker and Navy revolver were only able to dent the silver dollar. While a .357 Magnum could easily pierce the coin, the myth was busted because the .357 was not introduced until the 1930s—gunslingers did not have access to it. However, retrying the myth with lead coins instead of silver did yield large holes from both period weapons.|
|...save a man from being hanged by shooting the rope.||Busted||Firing at a rope with the pistols, even at point blank range, failed to break the rope. The bullets were merely deflected off the rope. A professional gunslinger armed with a more powerful Winchester repeating rifle managed to shoot and break the rope, but it required multiple tries to pull off. With the difficulty involved in shooting and breaking the rope, the myth was considered busted. The gunslinger also commented that it would have been easier to just shoot the executioners.|
This myth was part of a well-known engineering cliché: "Like a lead balloon, you cannot make a concrete glider fly."
|A glider can be made out of concrete.||Plausible||Adam's glider made a flight of over 34 ft (10 m) from a height of 9 ft (2.7 m). Jamie's took a nose dive. Also, an expert noted that making a glider out of concrete 'is' possible and that the Germans experimented with the idea during World War II. After the test, the MythBusters decided that making a concrete glider is possible, but highly dangerous and impractical since the brittle concrete would shatter once it hits the ground.|

|The vortex from a passing train can suck a person onto the tracks.||Busted||Although small-scale testing with model trains in a wind tunnel showed a vortex, the more dominant force when running the full size train was the air turbulence running alongside and away from the train. The force caused Ted, a dummy made of ballistics gel, to simply fall down where he stood rather than be drawn into the train's wake, and also violently pushed around an empty stroller tethered onto the platform alongside. Despite the lack of suction, the MythBusters agreed that the turbulence was powerful enough in its own right to make standing that close to the train as it passes very dangerous.|
This is the last episode to use the original opening sequence and the last before filming started in high-definition.
A portion of this myth was revisited in "More Myths Reopened".
|A bullet can be shot into the empty chamber of another revolver.||Confirmed||The MythBusters were actually able to fire a bullet straight down the chamber of the test revolver. The bullet went in and lodged itself inside the chamber, matching the picture they had.|
|A sniper can kill another sniper by shooting straight through the scope. (see Carlos Hathcock)||Busted||Using a police industry-standard SWAT sniper rifle and standard police match ammunition, the MythBusters fired several shots at a scoped rifle mounted on a ballistics gel dummy. The bullet was unable to hit the dummy: it was either stopped or deflected by the multiple layers of lenses in the scope, leaving the dummy relatively unharmed. Without any clear evidence that a bullet can penetrate a sniper scope, the MythBusters decided to label the myth as busted.
This myth was originally labeled "busted", but due to much debate by viewers, it was revisited in episode 75. Using a period-accurate scope (this myth originates from reports of Carlos Hathcock in the Vietnam War), it was found to be plausible.
|During the Civil War, two soldiers' bullets collided in midair and fused.||Plausible||The MythBusters first tried to mount two Civil War rifles in front of each other so that when fired, the bullets (lead Minié balls) would collide in midair. However, this proved impossible because they were unable to get the guns to fire at the same time. Instead, they aimed a single rifle at a bullet suspended in the air. The fired bullet hit dead center, and the MythBusters found that both bullets had fused into a single mass. Though very unlikely, it is possible for two bullets to collide and fuse in midair.|
This myth was brought up by concerned viewers, who feared that Jamie was in risk of suffering from the myth each time he banged two hammers together as part of a build.
This myth was revisited in "More Myths Reopened".
|If two hammers strike each other, or a hammer strikes an anvil, at least one hammer will completely shatter with lethal force.||Busted||Using a custom rig, the MythBusters repeatedly struck pairs of hammers together, but none shattered. Hammers with wooden handles merely snapped in two and hammers with metal handles bent. The MythBusters then decided to make the steel hammers harder and more brittle by adding more carbon and through heat treatment. In particular, they attempted to case harden the hammers. They heated the hammers to high temperatures and then coated the hammer heads in used engine oil. They also decided to have the hammers strike a more sturdy anvil instead of each other. However, during testing, the carbonized hammers merely bent at the handles without shattering. Though the myth was busted, some hammers come with warnings not to use them to strike another tool or hardened nail with excessive force; although no hammerhead shattered or chipped, high-speed footage showed particle dust flying in all directions, which presents an eye hazard.|
This was the first episode to feature the new opening sequence and be filmed in high-definition.
Anti-gravity is a hypothetical force that eliminates the effects of gravity on an object (as opposed to counteracting it). The MythBusters tested various devices that claimed to produce anti-gravity.
|Anti-gravity is possible.||Busted (for now)||After testing various contraptions that were allegedly able to defy gravity, the MythBusters found none of them could actually achieve "anti-gravity"; the contraptions (that did levitate) generated an upward force that balanced their downward gravitation. The myth was declared Busted (for now), because although they could bust the contraptions as anti-gravity machines, the idea of anti-gravity itself could not be busted through their tests.|
Christmas tree fires are common during the winter holidays, and cause millions of dollars in damage annually in America alone. The MythBusters tested one hypothesis on the cause of a Christmas tree fire.
|The heat generated by Christmas lights can ignite a Christmas tree.||Busted||After rigging a tinder-dry Christmas tree with 2500 C9 Christmas lights (for a total of 17.5 kW) and waiting for at least 40 minutes, the MythBusters were unable to get the tree to ignite by itself. Instead, they used an artificially created spark (simulating a short circuit) to set the tree on fire. Though the myth was busted, Adam and Jamie noted how quickly the tree caught on fire once it was ignited, warning viewers to be careful around their Christmas trees. Also, Adam and Jamie proved that a single extension cord can be overloaded with too many lights, causing the cord to produce significant heat due to its electrical resistance, which can burn the cord's insulation, which they theorize is the primary reason for Christmas tree fires.|
|...cure the pain of a jellyfish sting.||Confirmed||After receiving a sting from a jellyfish and then treating the wound with vodka, Kari noticed that most of the pain from the sting had disappeared. Vodka-based treatment seem to have worked about as well as the traditional warm water-based solution.|
The MythBusters test various holiday myths.
If a frozen turkey falls, it can...
|...crush a foot.||Confirmed||The frozen turkey completely crushed a ballistics gel foot, breaking many of the simulated bones embedded in it.|
|...crush a dog or cat.||Plausible||Two ballistics gel replicas of dogs were used and were completely crushed. When taken to a vet for analysis, the vet stated that if the dogs managed to survive their injuries, their prognosis would not be good. The myth was deemed plausible because the MythBusters were unwilling (and unable) to test the myth on real animals.|
The following myths state that a turkey can be cooked with...
|...a microwave radio.||Busted||The MythBusters were unable to attach the turkey to a full size radio antenna, though the manager stated that the antenna only used several watts of power compared to the several hundred used by microwave ovens. The MythBusters then tried to test the myth on a smaller vehicle-mounted microwave dish, but the only heating recorded was from sitting in the sun.|
|...a radar.||Busted||The MythBusters attached the turkey to the spinning radar antenna on the SS Jeremiah O'Brien, but when measured, they found that the turkey actually lost heat. Frustrated with the lack of results, Tory inserted an explosive stuffing into the turkey and put it in a microwave, resulting in a large explosion.|
The MythBusters tried several household methods in an attempt to prevent a freshly cut Christmas tree from shedding its needles over six weeks. One can keep needles from falling off the Christmas tree by adding...
|...fertilizer.||Busted||Fertilized Christmas trees lost the most needles and they became very discolored.|
|...bleach.||Plausible||The bleach was tied with nitric oxide at least needles lost, but the tree looked sickly.|
|...lemon lime soda.||Plausible||Lemon-lime soda was somewhat effective in retaining needles.|
|...pain reliever.||Plausible||Pain reliever was somewhat effective in retaining needles.|
|...nitric oxide from Viagra, referred to as "Santa's little helper" on-show as a form of self censorship, and that brand name was never mentioned on the show.||Plausible||The nitric oxide was tied with bleach at least needles lost, but the tree looked sickly.|
|...hairspray.||Plausible||Though declared the winner for being both the best-looking and among the best in terms of controlling needle loss, the added flammability of the hairspray to the drying Christmas tree could increase the tree's natural fire hazard risk.|
|...urethane.||Plausible||Urethane was somewhat effective in retaining needles.|
|...nothing (control).||Busted||The tree that received normal water lost more needles than any other tree except the one that received fertilizer.|
The MythBusters created a Rube Goldberg machine using Diet Coke and mentos.
|The MythBusters can build a successful holiday-themed Rube Goldberg machine within a week's time.||Confirmed||Though not an actual myth, the MythBusters decided it would be fun to build a holiday-themed Rube Goldberg machine. Using various household objects such as Mentos, Diet Coke, a bowling ball, various toys, and a roast turkey, the MythBusters appeared to create a successful Rube Goldberg machine that knocked Buster out of a chair after several tries. In the unedited version of one take (on the MythBusters Discovery website, probably the second trial from the episode), problems with the objects prevented the machine from running smoothly on its own, prompting the MythBusters to force it to work all the way through. Finally on the 10th trial, they successfully made the machine work all by itself. Although they did have much experience with creating Rube Goldberg machines in the past, the time constraint given for this particular one almost proved too much for them to handle (usually, it takes them two to three weeks to build a machine and a few days to shoot it; with this particular one, they only had a week to build and shoot it).|
During World War II, an Allied airman, Alan Magee, fell out of the underside ball turret of his B-17 at 22,000 ft (6,706 m) and survived. The MythBusters test one version of this story. According to the explosives expert used for the episode, this was the largest explosion executed for MythBusters up to that time with 500 lb (227 kg) of dynamite and detcord and was ignited with 2 blasting caps as Adam mentions in the dialog, one for the detcord, and other for the balloons. The resulting explosion travelled at a velocity of 21,000 ft (6,401 m) per second, destroying the train station and killing the airman proving that it was impossible for a bomb shockwave and human body to equalize pressure.
|A 22,000 ft (6,706 m) fall is survivable if one falls through a glass ceiling, and a 1,000-pound (450 kg) bomb explodes below oneself.||Busted||In both the small-scale and full-scale tests, the MythBusters observed that the shockwave from the blast had little effect on the speed of falling bodies. Also, the shrapnel and shockwave from the explosion would most likely kill the falling person if the fall itself did not.|
Throughout the series, Jamie had always pressured his M5 Industries employees and MythBusters production staff to turn the lights off whenever they leave a room to save electricity. The Build Team tested whether Jamie was correct in his assertion. During this myth, Grant and Kari visited the Livermore-Pleasanton Fire Department in California to see the Centennial Light.
|Due to the power surge required to turn on the lights, leaving a light on will save electricity.||Busted||Through numerous tests, the MythBusters calculated that the power surge from turning on a light would only consume as much power as leaving it on for a fraction of a second (except for fluorescent tube lights; the startup consumed about 23 seconds' worth of power). Furthermore, the wear and tear of turning the light on and off repeatedly did not reduce the bulb's total life expectancy enough to offset the increased electricity usage. Therefore, it is far more economical to turn a light off rather than leaving it on.|
