Set of Rods with Ball and Ring
This set of rods with ball and ring is ideal for demonstrating the expansion or contraction of metals.
- This set includes two brass rods with wooden handles with one bearing a ball at its end and the other a ring. The diameter of the ball and of the hole in the ring is about 25 mm.
- When the ball heats up, it will no longer be able to fit into the ring due to its expansion.
