This retro lamp was originally invented in 1894 by Nikola Tesla, but the bulb we recognise today was created by James Falk in the 1970's and has been a popular home decor item ever since! Perfect gift for a teenager, adult, or even as a night light for a pre-teen.
There are lots of demonstrations and experiments using a plasma ball on YouTube for anyone who is learning about physics or electricity conduction,.
How do they work?
Plasma balls are clear glass ball filled with inert gases. with a high-voltage electrode at its centre. Plasma filaments extend from the electrode to the glass when the lamp is turned on, creating fascinating moving beams of light. When you touch it the filaments are drawn to you, it's like being able to make your own lightning bolts!
Please note that the glass has been hand-blown so there may slight imperfections in the glass. This is normal with any glass dome of this size.

Powered by a 12V adaptor.
