Product Details

Here’s a paradox—a device that remains balanced when a heavy plastic tube dangles from one end while being supported at the opposite end by a single fingertip. Remove the tube and the device falls. How can this be? It’s center of gravity! This simple device will be a real show-stopper as you introduce your students to the concept of center of gravity. Includes demonstration instructions.

Concepts: Center of gravity, balance, stability.
Time Required: 15 minutes
Materials Provided: Acrylic finger balance, plastic tubing.
