As seen in "MythBusters: Vodka Myths".

Finding: BUSTED

Explanation: In 2001, around 40 cars and trucks welded together in a horrific traffic accident inside Switzerland's Gotthard tunnel. The heat and force of the massive collision caused the automobiles to literally melt into a giant ball of destruction.

The MythBusters uncovered a similar story of a head-on collision between two semitrucks. Supposedly the crash was so powerful the truck cabs welded together at the point of impact and smashed a compact car caught between the two like a metallic pancake.

MythBusters Jamie Hyneman and Adam Savage rigged up two semitrucks in an abandoned expanse of highway to crash test the tale. After securing an equidistant pathway for each auto, they sent the 35,000-pound trucks barreling toward a compact car at a combined speed of 70 miles per hour.

Although the epic crash sent semi shrapnel flying for the hills, the force and heat of the moving metal weren't enough to weld the trucks together, and the MythBusters decided that — even if the trucks had been moving faster — the result probably would have been the same. The car even escaped the carnage, since the initial impact shot it out sideways instead of smashing it between the truck cabs, and wrecked this myth good and proper.
