World’s Largest Nerf Gun

Mark Rober, a former NASA engineer, makes the world’s largest Nerf gun.  Not only is this amazing, its even more entertaining .Rober managed to create  a gigantic 4-foot tall version of the Nerf N-Strike Maverick that shoots huge  foam darts at approximately 40 mph using a 3,000 PSI air tank.  I really need to get my hands on one of these pronto.
