Mark Rober said he built the supersized Nerf toy mostly to survive in the workplace.
"People have these Nerf dart wars at work," Rober explained on a YouTube video showing off his handiwork. "In an effort to keep people from picking on me, I decided to create the world's largest functional Nerf gun."
The gun is powered by a paintball canister capable of shooting 3,000-pounds-per-square-inch.
That's a little too powerful for Rober's needs so he's modified the gun so each blast of air pressure that fills the gun can shoot off five shots before it needs a refill.
