Best way to keep kids engaged with educational toys
This 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 excites filaments that strike inside the globe. When you touch the globe, these filaments are attracted to the spot. This globe runs on both AC power and batteries and is 20cm in diameter.
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 will move as the gas around it heats up, and the gas becomes more buoyant, taking the filament along for the ride.
Simply plug it in and turn it on. Placing your hand or finger on the globe will allow you to? control? the strongest and brightest filaments.
The perfect and unique gift idea for kids and adults who love science and all things mesmerizing!
