1. Air Pressure
2. Newton's Laws as they pertain to forces and acceleration
|Step(s) to Follow||Expected Result|
1. Turn on vacuum pump to remove air.
2. Wait until pump gets quiet (air is removed.)
3. Use the sharp object to puncture the tape on the side of the tube nearest the vacuum hose.
|Ping pong ball is ejected from the tube, traveling at Mach 1, and goes THROUGH the target pop can|
Under NO CIRCUMSTANCES should the vacuum cannon be fired at a person! Although the ping pong ball doesn't have much mass, it will be moving at an extremely high rate of speed and, thus, could cause considerable damage to a person.
