This brass ball fits easily through the matching ring when they are both at room temperature. Heat the ball in a flame, and it expands so that it no longer fits through.

Comments about Arbor Scientific Ball and Ring Apparatus:
the ring and ball and threaded rod seemed good. The attachment of the wooden handle to the shaft didn't seem particularly robust. I suspect it will need attention after a year or two of use. It seems to be of acceptable quality for the price, however.
