5N20.25 - Tesla Coil - Plasma
Remove the standard tip from the hand held Tesla coil and plug in the light bulbs that have been modified for this purpose. You now have a plasma ball.
Different effects may be produced by adjusting the intensity and touching your fingers to the bulb.
The Illuma Storm and the Pickle Jar Plasma Globe are nothing more than Tesla coils that are illuminating partially evacuated gas globes. These are used mostly for plasma displays. There are two sizes of the Pickle Jar Globes available. Connect the small pickle jar globe to the small vacuum pump and evacuate for 2 minutes before pinching shut the vacuum tubing with the pinch clamp. Evacuate the the larger pickle jar globe for 3 minutes.
The color of the plasma depends on the type of gas or gasses in the globe.
