GSC Go Science Crazy Free Fall - Guinea and Feather 
A great classroom demonstration to show how different objects fall in a vacuum. The plexiglass cylinder is capped with a hard rubber closure at one end. A hose connector is fitted to the opposite end and is used to attach a vacuum pump (not included) to evacuate the air. When a vacuum is pulled in the tube and the tube is inverted, the disc and feather will fall at the same rate.
