Plasma Ball Tesla's Lamp 15cm dia

The mesmerising Plasma Ball is a true scientific icon, originally created by Nikola Tesla in 1894 during his experiments with high voltage currents. This scientific marvel demonstrates the properties of electrical discharges, which you can control with your fingers as you touch the lamp. The plasma globe is a sealed glass sphere that has most of its air replaced with 3 noble (inert) gases – neon, argon and xenon. A high frequency alternating current electrode is in the center, which discharges and excites filaments that strike inside the globe. When you touch the globe, these filaments are attracted to the spot, creating stunning visual effects. This globe runs on AC power and measures 15cm in diameter, making it the perfect geek gift for teens and adults who love science and all things mesmerising! However, it's important to note that this item should not be placed near sensitive electronic equipment. Additionally, it's not suitable for people with a pacemaker due to the strong electrical field it generates.
