Ring and Ball

This demonstration shows thermal expansion in solids. At room temperature, the ball fits through the ring. When the ball is heated, it will not pass through the ring. If both are heated, the ball will pass through the ring.

* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.

Setup:

Place the ball, ring, and heat gun on the demo table.

Use the heat gun to heat the ball, or both the ball and the ring.
