Description: This demo uses a tesla coil to illuminate a fluorescent light bulb
The high frequency and high voltage will actually excite the gas in the fluorescent tube.

Equipment:

  • Table top tesla coil
  • Long florescent bulb
  • Circular florescent bulb
  • Large Clear light bulb
  • Neon gas filled tube

Setup Procedure:

  1. Test to make sure the tesla coil works and the bulbs light up.

Demonstration Procedure:

  1. Turn on the tesla coil by moving the switch down (three way switch).
  2. Either with the lights on or off, bring one of the florescent bulbs near the tesla coil.
  3. Repeat with the other florescent bulb.
  4. Bring one of the clear lights near it.
  5. The neon will glow red, and the light bulb will glow a purple color due to its gas composition.

High Intensity Ultraviolet Light
Do not stare at the spark gap. Dangerous amounts of UV radiation may be emitted.

High Voltage / High Frequency
Due to the high frequency high voltage, keep away from sensitive electronics.
Avoid long contact, as electrical burns may occur.
