guns

i remember playing with Nerf guns as a kid and getting into heated debates whether a bullet hit my opponent or merely skimmed them. Well, that debate wouldn't happen with this gun. 

YouTuber Giaco Whatever built a Nerf cannon capable of shooting through a Red Bull can, but also breaking the sound barrier. It fires at 400 psi and can travel more than 1,700 miles an hour. If that skimmed you, you'd know.

The video above shows this baby in action, and it's frankly pretty terrifying. Like look at this thing:

Not this dude. 

At the shooting range 

"I shot through the hamper he was carrying. It went straight through the back of his leg. He started crying like a little baby."
