Title: A plasma globe or plasma lamp was invented by Nikola Tesla.
Caption: A plasma globe or plasma lamp (also called plasma ball, dome, sphere, tube or orb, depending on shape) is (usually) a clear glass sphere 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 coloured light. The plasma lamp was invented by Nikola Tesla.
