The Ring & Ball Apparatus is a physics lab equipment used to teach heat, temperature and thermodynamics.
Ring and Ball Apparatus is used for demonstrating thermal expansion of metal. 
When the Ring and Ball both are at same temperature the ball easily passes through the ring. Heat the ball in a flame. Try to pass the ball through the ring, it will not pass. 
The ball expands due to increased molecular motion.
