Myth statement: If a pressurized scuba tank is shot, it will explode.
Status: Busted
Notes: When the tank was punctured by a bullet, it simply decompressed quickly, causing it to fly around like a compressed-air rocket. The team was only able to make the tank explode in the end by using explosives.
