Essential Physics Demo: Large Demonstration Electroscope

With quick set up and execution, Large Demonstration Electroscopes give educators more time to work with students.

The exciting demonstrations connect students to core physics and physical science concepts. Perfect for introducing a unit or as reinforcement after a lesson, these demos also explore the phenomena of the photoelectric effect and Einstein's extraordinary discoveries.

Rubbing the provided zinc plate with steel wool leaves a charge on the electroscope. When a strong UV light source (not included) is close to the plate, it frees the electrons, providing a fascinating viewing experience. Balloons are recommended but not included.
