NERF HEAVEN — Remember the patron saint of uncles everywhere who spent his winter developing a snowball machine gun so he could mercilessly pelt his nephews? Well, he’s back, and his newest invention may be his best yet.

Mark Rober — who used to work as an engineer for NASA, by the way — has invented the world’s largest functioning NERF gun and he’s showing it off on his YouTube channel.

With the help of Ryan and David from the YouTube channel Eclectical Engineering, the gigantic gun was made using a pressurized air can typically used for a paintball gun. How it works is that the air — pressured to 3,000 psi — is released into a firing chamber when the trigger is pulled. That chamber is regulated to 80 psi and pushes out the darts. One can of air lasts for 20 rounds.

Oh, and those darts? They’re made of pool noodles and toilet plungers, leave the gun at approximately 40 miles per hour and can actually stick to their targets (theoretically).

Rober’s exclamation point on his demonstration, which included knocking over stacks of red cups and skeet shooting, was using it in a NERF battle against his niece and nephews. To say the least, they were a little astounded to see Uncle Mark’s monstrosity of a NERF gun.

If you’re interested seeing the FrankenNERF gun destroy some watermelons with some 3-D printed projectiles, you can go to the Eclectical Engineering page for the video.
