The Electric Balloon Wand
1. Inflate 3-4 latex balloons, tie them to weights, and space them evenly apart.
2. Slowly pass the PVC near the balloons to see if they react.
3. Vigorously rub the fabric cloth on the end of the PVC.
4. Slowly pass that end of the PVC near the balloons to see if they react.
How it works:
Friction causes the cloth to transfer electrons to the PVC, which gives the wand a negatively charged statoelectric field. This field interacts with the balloons, causing them to move.
