Pith Ball Set

Pith Ball Electrostatics Set for Physics Labs | Static Electricity Demonstration

This pith ball set is a classic apparatus for hands-on electrostatics experiments that demonstrate how static charges interact. Each lightweight styrofoam pith ball is suspended by a string, allowing it to move freely when brought near a charged object. This simple setup makes it easy for students to observe attraction and repulsion as charged objects interact with the suspended balls, making it ideal for one-afternoon science demonstrations on electricity.

Pith Ball Set Features:
• Lightweight styrofoam pith balls
• Suspended by string for free movement
• Designed for static electricity experiments
• Simple and effective classroom demonstration tool

Wanna know how it works? Students can bring a charged object—such as a balloon rubbed on hair or fabric—near the pith balls to see how electrostatic forces cause them to move. Depending on the charge present, the balls may be attracted or repelled, helping students visualize otherwise invisible electrical forces.

Did You Know? Static electricity builds up when electrons move from one material to another, creating an imbalance of charge that can cause objects to attract or repel each other.
