Van de Graaff Generator — Electrostatic Demonstration Kit

Make hair stand on end. Generate 200,000-volt sparks. Demonstrate the physics of electrostatics in real time.

This desktop Van de Graaff generator produces high-voltage, low-current static electricity through triboelectric charging — the same principle that creates lightning. Place your hand on the sphere and feel your hair lift as charge accumulates on your body. Bring a grounded object close and watch centimetre-long sparks jump through the air.

What you can demonstrate:

• Coulomb's law — charge accumulation and repulsion
• Electric field lines using tissue paper streamers
• Faraday cage shielding
• Triboelectric series and charge transfer
• Lightning rod geometry

Specifications: 15cm polished aluminum sphere · 200,000V output (low current, safe to touch) · Rubber belt drive · AC-powered · Includes discharge wand and instruction guide

Used in university physics demonstrations worldwide.
