Purpose: To demonstrate high-voltage electrostatic phenomena.

Wimshurst machine, Leyden jar.

Use your own imagination, but some of the possible demonstrations are as follows:

1. Demonstrate arcing across several centimeters, indicating a potential difference of the order of 100 kV.
2. Charge the Leyden jar, and discharge it to produce a large spark. Recharge the Leyden jar; give each can to a separate student to hold; then reassemble and show that you still get an arc between the inner and outer cans. (The charge stays on the glass).
