Former NASA engineer builds world’s largest Super Soaker, firing water at 272 mph – The Verge

Summer is here, and that means its time to break out the water guns. Or, if youre YouTuber Mark Rober (formerly a NASA engineer), its time to build the largest water gun ever made (via Gizmodo).

Robers giant water pistol is a little more overpowered than the original backyard toy, firing jets of water at 272 miles per hour, with enough force to slice through a watermelon and shatter glass. But despite the giant scale, the supersized Super Soaker works pretty much the same way as the toy version: pressurized air is pumped into a chamber of water, and released with the trigger to shoot a jet of water. Robers version instead uses pressurized tanks of nitrogen gas and water for far more impressive results,. But hey, its all working on the same principles.

Rober is no stranger to building comically oversized childrens guns. Last summer, he put together the worlds largest Nerf gun. While that was impressive, the 40-mile-per-hour darts it shot barely hold a candle to the destructive power of the seven-foot-long water pistol.

The gigantic Super Soaker is definitely a custom, one-off build, though Rober does provide a build list of parts and CAD files should you want to try to cobble together your own. As a note: pressurized gas as used here is dangerous, and Rober is a trained engineer, so proceed carefully if youre trying this at home. This is not meant for human targets!
