decorative electrical device using high voltage discharge within a transparent enclosure containing an inert gas
A plasma ball with filaments extending between the inner and outer spheres
A plasma globe, plasma ball, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container. When voltage is applied, a plasma is formed within the container. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of colored light. Plasma balls were popular as novelty items in the 1980s.
