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 as you touch the lamp.
The globe is a 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 centre, which discharges and excited filaments the strike inside the globe. When you touch the globe, these filaments are attracted to the spot. This globe runs on AC power and is 15cm in diameter.
The perfect geek gift for teens and adults who love science and all things mesmerising!

Such a sweet toy that will grow with my daughter and be played with for years to come. She is 17 months and loves rolling it along our floorboards as well as discovering different little things we have hidden in the back of the truck. It’s so well made and is lovely to the touch.
It’s not easy to snag these pieces! Slowly adding to my collection. Love browsing Dragonfly Toys and seeing what they on available on my wishlist. Ostheimer is one of most favourite collection!
