Think a ping pong ball is harmless? Think again. Join Anthony and Tara as they create a ping pong ball vacuum cannon that packs quite a punch!

Materials Used:
– Regular vacuum or vacuum pump
– 8 ft of 1 1/2 inch PVC pipe
– 2 slip connectors
– 1 inch diameter brass pipe with tapered threaded ends
– Gas valve w/ screw threads
– Vacuum hose
– Plumbers epoxy
– Mylar
– Pipe wrench

Experiment Tips:
– Make sure the mylar is securely fastened to both ends of the pipe so they don’t release prematurely.
– Be sure to use some sort of bullet proof shield in front of your ping pong cannon to avoid injuries.
– Delicate items like empty soda cans and thin porcelain objects break the easiest.

Ping Pong Serve Record
The fastest serve ever recorded by a ping-pong player moved at about 70 mph (113 km/h).

Supersonic Speed
The lightweight ping pong balls have poor aerodynamics but are able to reach supersonic speeds! Despite their measly 2.3 grams, the balls delivered a startling amount of energy to targets: the equivalent of a 125 mile-per-hour fastball or a brick falling several stories.

How To Make Your Own
Steps on how to make a ping pong ball vacuum cannon of your own.
