Thermal Expansion Demonstration Set

From the Manufacturer:
"This Set is an excellent device for demonstrating thermal expansion. Set includes brass ball and ring with wooden handles.

When cool, the ball easily fits through the ring. Heat up the ball with a gas stove and it no longer fits through the ring!"

Experimenting with the Thermal Expansion set requires the use of a heat source. Please use with caution.

The Expansion Rods are approximately 8 inches long.
