A bricklayer hoisting a wooden barrel full of bricks with a pulley from the top of a three-story building could be injured repeatedly.
The MythBusters were able to injure Buster by hitting him with the descending barrel as it pulled him up, but the barrel would not break and spill its load until deliberately weakened by removing hoops and dropping it on a sharp edge. This allowed Buster's weight to overcome the broken barrel and fall, while a quick-release mechanism in Buster's hand holding the rope allowed the barrel to be dropped a second time for the third impact. But there was no evidence of the myth happening; the source of the myth appears to be a joke book. This test marks the first time Buster was broken in the course of an experiment.
Since ballistic gelatin has the same electrical resistance as a human body, the MythBusters rigged a dummy with a urination valve and electric release that would trigger with exposure to current. Even wetting the feet and removing shoes failed to trigger the release, due to the urine stream failing to stay laminar and solid enough to complete a circuit. A larger valve failed to create a solid stream, but setting the dummy unrealistically close to the rail finally succeeded. A spinoff of this myth was tested in Myths Revisited. In this episode, the "genitalia" region of the dummy is censored, and no reference is made verbally, instead referring only to the urination process.
While testing the myth at a train yard, the yard's operators gave Adam permission to test a "mini-myth" with one of their engines:
Placing a coin on a train track is sufficient to derail a train.
Adam placed four different types of coin on the track at the same time, but none of them had any noticeable effect on the engine. All that happened was that the coins were flattened and partially melted by the intense friction generated as the engine passed over them.
Most eel-skin wallets are not made from electric eels, but rather from a fish called a hagfish which does not produce an electric charge. Data written to a set of test cards were not affected in any way from this leather exposure, nor by direct exposure to an eel in a tank. In addition, further tests were conducted to see how much magnetism would it take to 'wipe' a card, and was found to be about 1,000 gauss, far above what the average person may encounter.
