I3-16: COLLAPSE OF CAN - LARGE PUMP

I3-16

Demonstrate the forces created by atmospheric air pressure.

Start the mechanical vacuum pump, then place a soda can firmly on the top gasket around the pump opening. In a couple of seconds enough air is pumped out of the can so that the can collapses with a bang, jumping off the pump.
