PITH BALLS ON STAND
Product Description
Pith Balls on Stand are lightweight, spherical objects typically made from dried plant pith (spongy plant tissue), suspended from insulating threads and mounted on a non-conductive support structure. These classical electrostatics demonstration tools are used in physics laboratories to visually illustrate principles of static electricity, charge induction, electric forces, and Coulomb’s Law. The balls are extremely lightweight and react readily to electrostatic forces when charged objects are brought nearby, making them ideal for teaching foundational electricity concepts. The stand is usually composed of a plastic or acrylic base and vertical support to ensure stability and electrical insulation during experiments.
