Video Clip SS276149 (Tesla Coil Arching With Man’s Tongue)
Footage of an electrical discharge, produced from a Tesla coil, arching towards a man’s tongue.
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity.

He used these coils to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires.
Today their main use is for entertainment and educational displays, although small coils are still used today as leak detectors for high vacuum systems.

Nikola Tesla was born on this day in 1856.
Aged 35 (and a half) Tesla delivered a talk here at the Ri on AC power that was so spectacular, audiences flocked back the next night for an encore.
We love a science demonstration, and judging by his sprawling lecture desk, so did Tesla…
120 years after Tesla stood in the Faraday theatre (in 1892) we recreated a demonstration of his Tesla coil in the 2012 Christmas Lectures: https://youtu.be/5piP_qfDvBA?t=4s

Recently we stumbled upon this cheap high voltage converter on Amazon which claims a boost from 3-6V to 400kV.
Although really skeptical about the 400kV claim, a lot of comments indicated that it did boost at the very least to 10kV so we got one of these to test it out.

Using a 3V battery to power the circuit
And boom! There we go, that’s how you light up a CFL light bulb using a 3V battery!
If you do have access to a plasma globe or a tesla coil, things become a little bit more simpler:
Wireless (but not free) means to power a CFL light bulb
The way CFL light bulbs works is by exciting the electrons in the lamp and when they return to the ground state they radiate ultraviolet light. This emitted light is converted to visible light when it strikes the fluorescent coating on the glass.
So it really does not matter how you decide to excite the electrons to the higher energy state. It might be a high voltage converter, a tesla coil, a plasma globe, etc but all you need is a device that will kick those electrons inside the bulb from their ground state to the higher excite state. That’s all you need!
Have a great day!
