World’s Largest Super Soaker Is Verified By Guinness World Records

Largest Super Soaker

The minute my kids see something on TV or online, they want to buy it / build it / steal it.

“Can we make slime?”

“Can we get a t-shirt cannon?”

“Can we get a new mommy?”

I usually say no (though I seriously thought over that last request) but if the kids see this massive Super Soaker, well, I might have to cave in because I WANT THIS GIANT SUPER SOAKER.

Last summer, former NASA-engineer-turned-YouTuber Mark Rober built the world’s largest NERF gun.

This summer, Rober built himself a custom Super Soaker.

He’s like a real-life Phineas, or Ferb, depending on his accent. Rober’s soaker uses nitrogen tanks to shoot, and gas to pressurize a tank of water, to absolutely destroy his intended targets.


“Introducing the Guinness World Record Largest Super Soaker ever at 7-ft long!! This could definitely shoot Ralphie’s eye out.”

If you’re in the market to build one of these monster water cannons, he provides step-by-step instructions. Best of luck. Get extra insurance first.
