Thanks to KSL for making us aware of this video.
Mark Rober—a BYU graduate and former NASA engineer—has put his education to work creating machines every little kid dreams of. Last winter, he created a snowball machine gun in a video that has garnered over 4.5 million views followed up that summer with a video showing the world's largest nerf gun that has over 18.5 million views.
This summer, he designed a Guinness World Record winning super soaker at 7 feet long that squirts water at 272 miles per hour at eight times the pressure of that of a firetruck hose.
There's no doubt about it, this is one powerful water gun!
