Do you want to be a mad scientist... or maybe just look like one? Well, the Plasma Ball, originally designed at the Exploratorium, will help complete your transformation. The glass contains a mixture of gasses that turn into a plasma when exposed to the electromagnetic energy emanating from the coils in the base. The streaming lightning will respond to your touch.
Large lightning Ball measures about 8 inches in diameter, and the small one measures 3 inches.
Includes AC adaptor
