ABSTRACT:
An amusement device comprising a gas-filled plasma discharge tube; an electrode adjacent an end of the tube for coupling high-frequency, high-voltage energy into the gas in the plasma discharge tube; an ionization energy supply operably connectable to a source of electrcity for producing an adjustable high-frequency, high-voltage energy at an output thereof having an upper limit sufficient to ionize the gas in the plasma discharge tube without a ground return by utilizing the electrical capacity of the surroundings to provide a reactive impedance for plasma tube current to flow into, the electrode being operable connected to the output; and, a control circuit operably connected to the ionization energy supply for adjusting the level of the high-frequency, high-voltage energy at the output between levels causing ionization of the gas in the plasma discharge tube to occur in differing amounts as a function of a changing stimulus connected to an input thereof. There are embodiments as a light saber, an emotions meter, or the like, and a "Dancing Plasma Fire" device driven by an audio source. The preferred electrode capacitively couples to the discharge tube.
