I don't wanna grow up. Ever. I want to be just like this guy... a brilliant NASA engineer (former) isn't content to sit idle and put his smarts to good use. Well, fun use anyway. He created the worlds largest, fully-functional Nerf gun!
Pretty safe to say that you'd win ANY Nerf battle with this gun. Your opponents wouldn't stand a chance. Nerf toys are supposed to be safe though... but I'm guessing all bets are off when it comes to this massive target shooter.
