The Shockwave t-shirt canon is one mean looking machine. I'm not going to lie, if I saw this being wheeled out during half-time at a basketball game, I would be more than a little frightened.

Developed by Team 254 Robotics from Bellarmine College Preparatory and NASA, the Shockwave t-shirt canon is capable of launching three t-shirts in a second. According to Gizmodo, it "has a range of 150 yards, and an ammo capacity of 400 shirts." Wild.
