Comments: The center of gravity disk is a cardboard disk with a weight hidden within, to move the center of gravity from the physical center of the disk. One side of the disk has a spiral pattern radiating outwardly from the physical center, and the other side has a spiral pattern radiating outwardly from the center of mass. Throw the disc up in the air and allow students to see that it's rotating around the center of mass.
