Suitcase Gyro

Purpose:

To demonstrate a conservation of angular momentum.

Procedure:

A relatively large gyro wheel is bolted firmly on the insides of a suitcase. Using the Roto-zip tool spin the wheel pretty fast and close the suitcase. Make a student walk with the case on a straight line and make sharp turns.

Hints:

Perhaps spinning the wheel out of sight will be more dramatic.
