Ring & Ball Set


Product Description

Classic heat demo. You have two separate wands. There is a solid metal ball on the top of one and a metal ring on the top of the other. When the wands are at room temperature, the ball slides comfortably through the opening in the ring. The ball is then heated in a propane flame. When you attempt to slide the heated ball through the ring, it will not pass. Great way to demonstrate that metal expands when it is heated. You can then try various combinations of heating the ball, the ring, the ring and the ball, and plunging both or either in cold water. Hours of fun and amazement.
