Gravesande's Brass Ball and Ring Apparatus giant Hand Whirling / Adjustable Slits:Gravesande's Brass Ball and Ring Apparatus serves as a practical tool for showcasing thermal expansion concepts and demonstrate the effects of heating a metal. Students can observe the effects of temperature changes on the expansion of a ring and its effect on the passage of a metal ball. The size of the brass ball is precisely matched to the brass ring, ensuring that even if the ball is significantly warmer or the ring is significantly cooler, the
