1J10.10 - Map of a State
Hang the Map of the State and find the center of gravity or throw it up into the air and observe it rotating about the center of mass. LED's may be inserted into the map to show this more visually. Alternatively, you may also use stick on dots or rings to help observe the center of rotation.
