Last year Mark Rober, a former NASA engineer, created the world’s largest Nerf gun. That gun was capable of shooting darts at 40 MPH and was awesome.

Not only is this bad boy seven feet long, it shoots at 2,400 PSI and hits 243 MPH. So naturally, he had to test it out by blasting away at some kids in a very unfair water gun war.
If your interested, here’s how he made it.
