Classic electrostatics demonstrations with dramatic sparks

The Winsco Van de Graaff Generator brings the excitement of electrostatics to life through striking demonstrations of charge, potential difference, and electric fields. With its durable construction, smooth operation, and consistent performance, this classroom staple provides a safe, hands-on way to explore the fascinating world of static electricity.

The Winsco Van de Graaff lets students see and feel electric forces in action — from hair-raising charge buildup to crackling sparks that make electricity unforgettable.

Why Teachers Love the Winsco Van de Graaff Generator
  • Balance of Engagement and Safety: The generator produces sparks from 8 inches to as high as 12–15 inches. Yet with a maximum continuous current of just 10 microamps, it allows students to explore electricity up close without risk.
  • Built to Last: Rugged metal dome and stable base ensure long-term durability and easy maintenance.
  • Highly Versatile: Supports a wide range of electrostatic demonstrations — from charging conductors to operating accessories like the electric whirl or electroscope.

What You Can Teach with the Winsco Van de Graaff Generator

The Winsco Van de Graaff Generator turns abstract electrical concepts into hands-on exploration and experimentation:

  • Charge Accumulation & Transfer: Demonstrate how friction generates the static charge and the belt transfers the charge to the dome.
  • Electric Fields & Potential: Visualize field strength and voltage differences with sparks, foil strips, and streamers.
  • Conductors & Insulators: Compare how different materials hold or discharge static charge.
  • Grounding & Shielding: Explore the principles of grounding and Faraday cages in action.
  • Energy Conversion: Convert mechanical energy into electrical potential to reinforce conservation of energy principles.

Grades 4–8: How Students Can Use the Winsco Van de Graaff Generator

The Winsco Van de Graaff Generator is a show-stopping way to introduce electricity in grades 4–8 using safe, memorable, hands-on experiences.

High-engagement investigations for upper elementary & middle school

  • Hair-Raising Charge Demo: A student on an insulated stool touches the dome and watches their hair stand up. This makes the idea of like charges repelling
  • Conductor/Insulator Sorting Lab: Students test materials (metal spoon, plastic ruler, wood stick, rubber, cardboard) to see which ones quickly discharge the dome and which don’t.
  • Grounding Surprise: Have students hold a grounded object near the dome and predict what will happen. Use this to talk about why sparks jump and how grounding provides a path for charge
