Former NASA Engineer Makes Himself World’s Largest Water Gun

Introducing the Guinness World Record Largest Super Soaker evaa at 7 ft long!! This could definitely shoot Ralphie’s eye out. Shout out to my buddy Ken Glazebrook of NASA JPL fame for his significant help on designing and fabricating the gun.

A mechanical engineer from California built the world’s largest Super Soaker, capable of shattering glass with a forceful stream of water.The massive water gun managed to slice watermelons, bananas and hot dogs in half, split open a soda can and shatter a line of wine goblets with jets of water traveling 272 mph.

Rather than harness pressure via a hand pump, it gets its water pressure from a tall nitrogen tank hidden in the handle, which shoots the water with just a little more oomph than you’re probably used to, like 2,400 psi and 243 miles per hour .Mark’s jumbo Super Soaker can cut through all kinds of stuff, including glass, food, and soda cans.


We worked out the scale that he was going for and drew out a grid over a profile picture of the original Super Soaker.Then transferred the grid to a sheet of plywood and used it to draw out the picture to scale. Jus simply cut it out with a jigsaw and built a simple frame.
