Plasma Lamp was invented by Nikola Tesla. This plasma globe or plasma lamp (also called plasma ball, dome, sphere, tube or orb, depending on shape) is a clear glass sphere (3 inches in diameter) filled with a mixture of various noble gases with a high-voltage electrode in the center of the sphere. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of colored light. Similar to aurora, but enclosed in a glass bulb.
Experience the wonders of physics and learn about the properties of high voltage and high frequency electrical energy. Also Demonstrates electrical discharge (similar to an electric arc).
