ABSTRACT:
An apparatus for generating sparks over a selected area to be used for theatrical effects. Metal wire having a diameter in the range of 0.020-0.125 inches is provided by two, independent supply sources. Each wire supply source is coupled to a wire guide which imposes synchronous, linear movement to each wire source at a selected rate. Each wire source is coupled to a tip assembly which places the terminus of each wire source adjacent one another. The positive and negative electrodes of a direct current power source are electrically connected to a respective terminus of each of the pair of wire sources, the output of the direct current power source is amplified to voltage sufficient to atomize the wire when the power source is short circuited. The atomization of the wire results in the production of heated, metallic particles simulating generated sparks. A source of compressed air is disposed adjacent the point of atomization. The atomized particles are disseminated across an area determined by the force imposed thereon by the compressed air.
