The scientists on a show on the natgeo channel asked this very same question. Since there is no such thing as a bulletproof water balloon, just how many do you think it would take to actually stop a bullet from one of the most powerful handguns in the world? Water is an amazing substance with incredible properties, but can it truly stop a bullet? How many water balloons would it take? One, four, nine, twenty-nine water filled balloons?
Take a guess. We bet its not what you think.
