This experiment demonstrates the fact that objects of different masses fall at the same rate in a vacuum. The plastic cylinder has rubber stopper closures on both ends, with one end having a hose connection that is used to evacuate air. When air in the tube is pumped out via a vacuum pump (not included), the coin and feather included with the kit will fall simultaneously because there is nothing causing resistance anymore in the tube.

We have vacuum pumps for sale separately. They are available with and without a pressure gauge attachment.
