04 Nov Purdue Know-how learners develop supersonic ping pong gun



Purdue Faculty of Know-how professor Mark French tasked his doctoral learners to understand his vision for the world’s initial supersonic ping pong gun. Their air-run Bazooka launches the inefficient ammunition at Mach 1.23, speedier than an F-16 fighter jet. Inspite of their deficiency of mass, the featherweight balls pack a large amount of electricity.

    This is a great video – inspired a father-son project for the 2015 OMSI (Portland, OR) Maker Faire. After 200+ hours of optimization, we hit 566 meters/second with vacuum-air and 773 meters/second with vacuum-helium. If interested, see youtube channel davekni

    Hello! My Physics class is trying the same experiment, minus the pressurized tank. However, upon puncturing the back of our tube, we often only hear a hiss, and the ball does not move. Do you know why this is? P.S. We are pulling a vacuum of 27 inches of Mercury. Thank you!

    Be interested in seeing the "Control" test, that is, the complete test done "without" the ping pong ball projectile.
