The “Lethal Pneumatic Ping Pong Ball Gun” is the work of Denver man Ron Kessinger. After firing off a few dry rounds, the guys fill some ping pong balls up with water and show why the gun deserves to have the word “lethal” in its name.
According to one witness:
A sheet of drywall was no match for them, and even particle board failed spectacularly when faced by a 1″ sphere of water.
