For demonstrating thermal expansion. Comprising a brass ball and a brass ring, each on its own rod with wooden handle. Whilst the ball will pass through the ring when cold, it will not do so when heated. However, if both ball and ring are heated to the same extent, the ball will pass, thus demonstrating the “expansion of a hole” effect.
