Description
This unit demonstrates the expansion of metal when heated and its contraction when cooled. When either the ball or ring is heated, the ball will not pass through the ring, but when cooled the ball passes through the ring freely. The ball and ring are mounted to insulated wooden handles to protect hands from the heat. A great introduction to expansion and contraction!
