So a guy wanted to build the world’s largest functional Nerf gun (VIDEOS)

Mark Rober tapped in some engineering friends to help craft him the Big Bertha of Nerf pistols to guarantee a win in every office or home foam dart engagement.

The inner workings include a 3000psi paintball tank for oomph and a PVC firing chamber regulated to 80 psi that will kick out a pool noodle/toilet plunger dart at 40 mph.

Then the Eclectical Engineering guys increased the firepower on the gun to obliterate watermelons after replacing the air system with a black powder cannon and swapping out the foam plungers for wooden dowels and 3D printed projectiles.
