Running the Demonstration
At room temperature the cold ball passes through the ring. Heat the ball in a flame and it expands, so it can no longer pass through. Cool it in water and it contracts close to its original size, after which it passes through the ring again. Heating the ring instead of cooling the ball also works: the hole in the ring widens as the metal expands, and the ball passes once more.
Hold both parts only by their handles, since the metal stays hot for some time after heating.
Why the Ball Grows
Heating makes the particles of the metal vibrate more strongly and move farther apart on average, so the volume of the ball increases. The change is small, but the close fit between ball and ring turns it into a clear pass or no-pass result.
