Paper Crossbow

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.

Helium Football

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.

Catching a Bullet in Your Teeth

The Build Team takes on the bullet catch magic trick and sees whether it is possible to do the trick for real.

Franklin's Kite

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.

Facts About Flatulence

In this myth, Adam and Jamie tested some of the more prevalent myths based on flatulence. Throughout the myth, the MythBusters were careful to use only 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).

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.

Helium Raft

Cell Phones on a Plane

Bullets Fired Up

Vodka can...

Salami Rocket

The MythBusters revisited the Confederate Rocket myth with some new information from viewers. This was revisited in "More Myths Revisited".

Splitting an Arrow

At the insistence of viewers, the team retested the popular arrow-splitting myth seen in the film The Adventures of Robin Hood.

Guns Fired Underwater

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?

Painting With Explosives

This myth originated from the episode "Do-It-Yourself, Mr. Bean" of the British comedy series Mr. Bean starring Rowan Atkinson.

Mind Control

Remote, non-consensual mind control can be achieved by...

Exploding Pants

This myth came from New Zealand in the early 1930s, where an epidemic of exploding pants had rampaged, injuring and even killing farmers.^[5] The culprit was a then-unfamiliar chemical substance that farmers began using in large quantities at the time.

The Great Gas Conspiracy

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 were tested to see if cheap fuel efficiency can be achieved with...

Air Duct Climb

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...

Laser Beam Dodge

Before Grant started the myth, he stated that he found that the highly visible, brightly colored light 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...

Infrared Beam Dodge

After getting through the visible lasers, Kari and Tory faced the real-world equivalent: infrared photo-beam detectors. They tested the following methods:

Glass Door Forced Entry

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. Adam and Jamie tested the following techniques in an hour-long practice session and during the test itself:

Fooling the Pressure Sensor

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 a person can successfully fool a pressure sensor under a glass case by...

Safecracking

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...

Scaling a Building

In a final twist, Grant and Tory challenged Adam to scale a 23-story building by using his suction cups as a cat burglar might in order to get to a helicopter on the roof.

Cereal Nutrition

A popular saying states that sugary cereal is less nutritious than its box.

Note: Adam and Jamie admitted in an interview that they tried an earlier test of this myth using rats in cooperation with a university. However, of the three groups they used, they found that one of the rats in the group fed cardboard ate the others in the sample when they returned. The decision was later made by Discovery to leave the segment unaired.

Steam Cannon

A diagram by Leonardo da Vinci blueprints a steam-powered cannon that Archimedes supposedly built.

The MythBusters Teeth Challenge

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. This was not aired in the US. However, on the Discovery Europe version, it is included in the episode.^{[citation needed]}

Whirlpool of Death

Whirlpools are an ancient maritime fear. According to the myth, a tidal whirlpool can sink...

Snowplow Flips Car

A fan claims that he saw a car capsize when a snowplow passed by in the opposite direction at high speed.

Diet Coke and Mentos

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 into trouble by their parents).

Stamp on a Helicopter

Shattering Subwoofer

Rough Road Driving

A spinoff myth was tested in "More Myths Revisited".

Fingerprint Lock

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 it 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...

Thermal Motion Sensor

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...

Ultrasonic Motion Sensor

Ultrasonic motion detectors note any Doppler shifts caused by a moving intruder. Kari, Tory, and Grant tested whether an ultrasonic motion detector can be fooled by...

Water Safe

This myth was based on a scene from the movie The Score, where Nick Wells (Robert De Niro) uses this technique to break into a safe containing a glass relocker.

Miniature Earthquake Machine

The MythBusters tested one of Nikola Tesla's publications.^[7]

Exploding Lava Lamp

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 ballistics gel torso with an actual human ribcage and a fake heart near the stove so that they could examine potential injuries:

Straw Through a Palm Tree

Primary Perception

The Build Team tested world-renowned polygrapher Cleve Backster's theory of primary perception.

Killer Cable Slice

Pottery Record (Archaeoacoustics)

Air Cylinder of Death

A compressed air cylinder can...

Gunpowder Engine

Sword vs. Gun

Rough Road Driving

Salami Rocket

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.

Tailgate Up vs. Tailgate Down

Exploding Lighter

The MythBusters tested the following myths concerning standard disposable butane lighters.

Gunslinger Myths

Using a Colt Peacemaker and a Navy revolver, the MythBusters tested whether an Old West gunslinger could...

Concrete Glider

This myth was part of a well-known engineering cliché: "Like a lead balloon, you cannot make a concrete glider fly."

See also Lead Balloon.

Train Suction

Firearms Folklore

A portion of this myth was revisited in "More Myths Reopened".

Hammer vs. Hammer

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".

Anti-gravity

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.

Christmas Lights

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.

Vodka Myths IV

22,000 Foot Fall

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 the other for the balloons. The resulting explosion traveled 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.

Lights On/Off

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.
