The plasma lamp was invented by Nikola Tesla, during his experiments with high-frequency currents in an evacuated glass tube, for his studies on high voltage phenomena. The modern plasma lamp design was subsequently developed by Bill Parker, a student at MIT.

This globe is filled with 3 inert gasses - neon, argon and xenon. A high frequency alternating current electrode is in the centre and when it discharges, it excites the filaments thaat strike the inside of the globe. Touch the glass to watch a tendril of plasma form.

Putting your hand or finger on the glass creates an attraction spot, as the human body has less resistance than the glass. This allows for a brighter, thinner tendril of plasma to form.

The filament moves as the gas around it heats up, and the gas becomes more buoyant, taking the filament along for the ride.
