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!
- 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
- Pipe wrench
- 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).
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.
