Free Fall Tower


Recreate Galileo's famous experiment by dropping objects off the Tower of Pisa. You can drop ping pong balls, golf balls, soccer balls or watermelons. Objects can be dropped in air or no air, with or without a parachute. The speed of each object is shown on a speedometer and a graph.

    I used this to prove to my skeptics about acceleration due to gravity. Loved it for alternative students.
