Cool Off With the World’s Biggest Super Soakin’ Water Pistol EVER
Former NASA engineer Mark Rober unveiled what he says is the "world's largest super soaker." See for yourself.
The seven-foot long gun is powerful enough to smash aluminum cans, break glass, and crush watermelons. Rober says it took six-months to build the soaker, which uses nitrogen gas and water to propel the water stream.
