Show your students how materials and substances can change in size when the temperature changes.

Unless the ball is heated or the ring cooled, the ball will fit freely and easily through the ring. Plastic handles of each ball and ring stick provide easy grip. Use this thermal expansion and contraction demonstrator for your science classes, teaching about matter changes (solids, liquids, gases), molecule changes, and more.
