This iconic scientific lamp was originally created by Nikola Tesla in 1894, following his experiments with high-voltage currents. The plasma ball demonstrates the properties of electrical discharges, which you can control with your fingers by touching the lamp.

The globe is a sphere in which most of the air has been replaced by three noble (inert) gases: neon, argon, and xenon. In the center, there is a high-frequency alternating current electrode that discharges and excites the filaments that strike the inside of the globe. When you touch the globe, these filaments are attracted to that location. This globe works with alternating current and has a diameter of 15 cm.

The perfect geeky gift for teens and adults who love science and everything fascinating!
