The myth "Seasickness -- Kill or Cure?" consisted of several parts, which were each individually called either Busted or Plausible.

Because Adam and Grant are very susceptible to motion sickness, they test non-pharmaceutical remedies for seasickness by...

Myth statement Status Notes
...using a cinnamon-flavored tongue spray. Busted The spray took no effect on Adam or Grant.
...taking a ginger pill. Plausible Both Adam and Grant endured the spin-chair for twenty to thirty minutes without experiencing any symptoms, however they decided it could not be confirmed as Seasickness is 'very individual' and depends on the person.
...using magnetized arm bands. Busted The arm bands had no effect on Adam or Grant. Some celebrities like Barry Manilow claim they work, but they nonetheless do not operate on any valid scientific principles.
...using an electro-shock wrist band. Busted The shocks mildly discomforted Adam and Grant, who nonetheless became sick.
...using a placebo, like a vitamin or a sugar pill. Plausible While Adam was not affected by the placebo, Grant was successfully tricked into thinking he had taken a store-bought sea-sickness medication and did not throw up. He had taken vitamin B12 and claimed it was the most effective remedy. By falling for the placebo all his test results had to be thrown out on the grounds of psychosomatic influence.

Tailgate Up vs. Tailgate DownEdit

This was revisited in More Myths Revisited.

Myth statement Status Notes
It is more fuel efficient to drive a pick-up truck with its tailgate down, rather than up. Busted Driving with the tailgate down actually increased drag on the pick-up and caused it to consume fuel faster than the identical truck driven with the tailgate up. It was later revealed that the closed tailgate creates a locked vortex flow that created a smoother flow of air over the truck. With the tailgate down, the trapped vortex was dissipated and the drag increased.

Finger in a BarrelEdit

The Build Team take on a myth that forms a staple of cartoon physics. This was revisited in Myths Redux.

Myth statement Status Notes
A shotgun plugged by a human finger will backfire and explode injuring or killing the shooter instead of the intended victim. Busted Both test hands (composed of ballistics gel of varying firmness) were completely obliterated by the shotgun blast. Neither had the volume or strength needed to plug the barrel to create enough pressure to cause it to explode. Even under ridiculous circumstances like having the barrel clogged with dirt, being sealed off by a 4-inch (10 cm) spike welded into the barrel and by being blocked by a simulated squib load, the gun still did not explode. The best results seen were minor deformations in the gun barrel.
