What former NASA engineer Mark Rober has built is no average squirt gun... heck, it's no average Super Soaker, even.
This sucker measures seven-feet long to make it the world's largest Super Soaker, according to the Guiness Book of World Records.
It took him six months to build the giant water gun, which fires a stream of liquid at 2,440 pounds per square inch and 243 miles per hour.
Better not get in its way.
