Shooting Through Liquid
Explanation: In the movie Kiss the Girls, a police officer faces off with the bad guy in a kitchen that's been pumped full of natural gas from the stove. The villain warns the cop that the muzzle flash from his gun will ignite the natural gas and blow up the both of them. To snuff out that pesky muzzle flash, the savvy officer snags a carton of milk, safely shoots through it and saves the day.
Curious about whether milk can really drown out a muzzle flash, MythBusters Tory Belleci, Kari Byron and Grant Imahara cooked up a methane-filled test kitchen and shot off a couple of rounds. Just like in the film, shooting through the milk carton caused no explosion.
However, when the team fired the gun without the milk muffler, there still wasn't an explosion. Frame-by-frame footage of the gun firing demonstrated that the muzzle flash lasted only 1 millisecond — not long enough to ignite anything. Even firing a powerful .44 Magnum couldn't cause combustion, which busted the myth.
In the movie, the cop could've safely shot away without the milk carton since the muzzle flash simply doesn't last long enough to spark a flame.
