Watch this video to see how to build a simple air gun. Well, okay... it might not be "that' simple, but anyways...
Gather your materials to start making this powerful air gun: PVC fittings, a valve, heat source, PVC pipes, rubber hose, pump, ice pick and a soda cap. Arrange all of the appropriate piece into the shape of a gun, screw the soda pop bottle cap onto the valve and glue it in place. Attach the air pump to the hose and the hose to the cap; glue the pump to the gun.
Just remember that PVC produces poisonous fumes when burned, so don't ignite it and stay safe!
