Plasma Globe Light Bulb

Mrs. Mandarich Explanation of Demo
A plasma globe contains noble gases which, when excited by electrical current, emit electromagnetic waves that are given off as light as electrons move to and from higher energy leveles. These high frequency EM waves can be harnessed to illuminate an old-fashioned fluorescent light bulb because these light bulbs actually function by utilizing mercury in vapor form and when excited, exposed to EM waves, light is given off from the bulb.
