Centripetal Force Toys

There are three experiments here demonstrating centripetal force. One experiment is a ball on a string that is whirled in a circle above your head. When the string is released the ball travels off in a straight line. The second experiment is a coat hanger with a penny. The penny is balanced on the tip of the hook and then the coat hanger is whirled in a vertical circle as the penny stays on the tip. The last experiment is a bucket of water that is also whirled in a vertical circle and the water stays in the bucket.
