Plasma globe

A plasma globe, also known as a plasma ball, is a device that demonstrates the properties of plasma, one of the four fundamental states of matter. The globe typically consists of a clear glass sphere filled with a low-pressure gas, often a mixture of noble gases like neon or argon. At the center of the globe is an electrode that generates high-frequency alternating current electricity. When the device is powered on, the electrode produces high-voltage ionization of the gas within the globe.
