What the Nerf?!?! Rapid Prototyping at its Best.

Today, an undergrad decided to shoot me with a nerf dart. His weapon of choice: PVC pipe blow dart, lung powered. In retaliation I went to the local hardware store. One ball pump, five feet of rubber tubing, one water hose nozzle, two feet of copper pipe, and three hours of work later I went hunting for undergrads. The rubber tube can hold 200 psi of air... need I say more?
