Students are always amazed by static tubes, and now the whole class can explore the forces of static electricity at an unbeatable price. The kit allows students to construct a static tube and then watch as the styrofoam pellets inside seem to move on their own. Static electricity causes pellets to attract and repel from different materials that are brought close to the tube. Discover which items have a positive or negative charge.

Kit includes:

• 16 clear tubes
• 32 plastic caps
• Styrofoam pellets
• Measuring cup for pellets
• Instructions and activities

Tubes like this usually sell for 3-4 dollars each. We include enough materials to create 16 static tubes. Each tube measures 8 inches (21 cm) tall and 1.5 inches (4 cm) wide. Not a toy. For ages 10 and up with adult supervision.
