Large Tesla's Lamp Plasma BallThe Large Teslas Lamp Plasma Ball is a hands on demonstration of electrical discharge, inspired by early high voltage experiments. Inside the glass sphere, a mixture of noble gasesincluding neon, argon, and xenonreacts to a high frequency alternating current electrode, producing glowing filaments that move and respond to touch. The larger globe size makes the electrical patterns more visible and dynamic, making it an engaging addition to desks,
