The World’s Largest Super Soaker

Last year, Mark Rober, an inventor and former NASA engineer, built the world’s largest nerf gun. This year, Mark and his buddy Bob Clagett followed that up by creating a giant, 7-foot-long Super Soaker water gun that’s fully functional and capable of shooting a water stream powerful enough to slice through watermelons and cans of soda. Watch Bob’s behind-the-build video, below.

“I made the world’s largest Super Soaker as a follow up to my World’s Largest Nerf Gun. It shoots at 2,400 psi and 243 mph. I destroy a bunch of stuff in slow motion and talk to the inventor of the Super Soaker Lonnie Johnson.”
