Expoding Gas Tank
Explanation: In Hollywood, it seems like all you need to blow a car to smithereens is a gun and a gas tank. A garage-full of flicks depict people destroying automobiles by shooting straight into to the tank, triggering a massive explosion.
But when MythBuster Jamie Hyneman bored into a Cadillac's full gas tank with a barrage of bullets, no such detonation went down. His six slugs simply ripped right through the tank and out the other side of the otherwise intact sedan.
With no flames to be found, Jamie's gas tank target practice busted the cinematic motor myth.
