Purpose: To demonstrate the effect of an electric field on charged particles.

*Demonstration currently being redeveloped

If you need this demo sooner rather than later let me know and I'll move its priority up.

Incense (to produce smoke), glass cylinder with metal top and bottom, light, video camera, high voltage power supply, metal ring containing electrodes.

The smoke filled cylinder (with electrode ring placed on the bottom) is illuminated and viewed with the close-up video camera. When 15 kV is applied, the smoke is seen to disappear, thus demonstrating the attraction of the (charged) smoke particles to the charged electrodes.
