Coin and Feather Vacuum Demonstration – 39.25" H Plastic/Rubber Tube (Transparent), Case of 10 Physics Experiment Kits by GSC International Inc.

The Coin and Feather Demonstration is a classic physics experiment designed to illustrate that objects of different masses fall at the same rate in a vacuum. This engaging educational apparatus provides a clear, visual understanding of gravity and the effects of air resistance.

Each unit features a durable transparent plastic cylinder with rubber stopper closures on both ends. One end includes a hose connection for evacuating air using a vacuum pump (not included). Once the air is removed, the included coin and feather fall simultaneously, demonstrating the absence of air resistance.

Sold as a case of 10 complete apparatuses, this set is ideal for classrooms, labs, and group demonstrations, allowing multiple students to participate in hands-on learning.
