Purpose:An illustration of centripetal force.
Procedure:Wrap the chain around the edge of the plywood disk making sure there are no twists in the chain. Spin up the drill slowly and bring it to full speed. Tip the drill downward and give a slight jerk back and the chain will fall off. The chain will be spinning rapidly enough to retain its circular shape for a short time as it rolls down the bench.
