Rotating Steel Ball

SKU Code: REMZ09

This apparatus has been constructed to demonstrate the ease of motion when a cushion of air is formed under an object. Initially, air is blown out of a small hole from under the ball. This forms an air cushion between the ball and the socket where the ball sits. This way, the ball which is very heavy and is normally difficult to move, can be rotated easily.
