Our eBay StorePendulum Wave Demonstration
The pendulum wave demonstration is a cross between science and art. It demonstrates how mass accelerates and decelerates as a response to the force of gravity. Nine 1" diameter steel pendulums will form wave patterns as they fall in and out of sync with one another. Some minor assembly is required. Instructions and teachers guide included.
