How Many Caulks does it take to stop a Bullet?
This video demonstrates a series of ballistic tests to determine the effectiveness of common household caulk in stopping various firearm projectiles. The experiment uses multiple firearms, including a .22 LR rifle, 9mm pistols, a .357 Magnum revolver, an AK-47, and an 8mm Mauser rifle, firing different types of ammunition at barriers constructed from caulk tubes. The results show varying degrees of penetration, with more powerful rounds easily passing through multiple tubes, while some success is noted with smaller caliber rounds.
