Description

The ball and ring is a well-worn classic among thermal physics demonstrations. The ball barely fits through the ring when everything's at room temperature. Heat the ball, and it no longer fits through the ring. But what happens if you heat the ring instead?

Most folks leave it there. But did the inner diameter of the ring expand or remain the same upon heating, The result of the demo is inconclusive. So a third demo is called for. The explanation for the result is also provided.

Details are in the included presentation. When I ran this demo in remote teaching, I conducted it live over Zoom, so I didn't record any video. That's why I'm casting this resource as a demonstration guide. Still useful to run while you do the demo in class.
