Remember the Plasma Ball sitting next to the bed in Fry's room in the 'Movie Ferris Bueller's Day Off'? That's what triggered my interest in plasmas all those years ago.

This is a 20 inch wide plasma ball (Plasma Discharge Flask) made from Pyrex® (impact and heat resistant) containing Neon, Xenon and Argon with a custom built power supply which runs at 30-50khz. This is one of the largest plasmas you'll find outside a museum although my video camera seems to be unable to recognize the blue colors in the plasma. This is actually not the largest plasma in my collection although it's the largest that I can carry by myself without assistance.

The globe in this video has more than one effect depending on the Power Supply used at the time (see linked images):
