Ball and Ring
Product Code : JL-LE-10615
The Ball and Ring (SKU JL-LE-10615, Cat. No. JSS-251/069) is a classic ball and ring apparatus for demonstrating the thermal expansion of solids. A brass ball is held captive to a brass ring by a chain, and the ring is mounted on a rod with a wooden handle. At room temperature the ball passes through the ring; once the ball is heated it expands and no longer fits, and it drops through again as it cools.

Frequently asked questions
What does the ball and ring apparatus demonstrate?
Thermal expansion of a solid: once heated, the brass ball expands and will not pass through the ring until it cools.
Why is the ball on a chain?
The chain keeps the ball captive to the ring, so it stays with the apparatus during the demonstration.
