About This Product
In the ball and ring experiment the brass ball passes through the ring when both are cold. When the ball is heated it expands and no longer passes through the ring. Once it cools it fits again, and heating the ring as well lets the ball pass through once more. This shows that solids expand on heating. The plastic handle is used to hold the ball.
