Ball and Ring Apparatus 9"H Metal Thermal Expansion Demonstration Physics Experiment Tool Pack of 10 By GSC International Inc.

Enable effective group demonstrations with this Ball and Ring Apparatus Pack of 10, designed to clearly illustrate the concept of thermal expansion in physics. Each unit measures approximately 9" H x 0.83" W x 0.95" L and provides a simple, visual way to understand how metals expand when heated and contract when cooled.

Each apparatus features a metal ball and ring mounted on an insulated handle for safer handling during experiments. When heated, the ball expands and cannot pass through the ring, while cooling allows it to pass through again. Built from durable metal and designed for repeated classroom use, each unit includes instructions, making this bulk pack ideal for labs, classrooms, and STEM learning environments.
