Abstract: The pyrotechnic entertainment product has an upright spindle that may be pushed into the ground for support until a coil in the spindle engages the top surface of the ground. The image of an upright dancing bull or other creature is secured to the spindle intermediate its opposite ends and is poised as if he were performing the steps of a Mexican hat dance. A pyrotechnic pinwheel resembling a sombrero is rotatably carried on the upper end of the spindle slightly above the head of the bull. When the pinwheel is ignited, it propels itself about the spindle like a spinning sombrero while emitting a colorful plume of sparks reminiscent of the energy, color, and excitement of the traditional Mexican hat dance.

Abstract: A system and method for generating special effects showers of sparks for use in theme park shows and rides. A flint rod is biased with fluid pressure against a cutting wheel of this system. When a clutch is actuated for a brief predetermined time period, a constant high speed motor is operatively connected to the cutting wheel, rapidly rotating it. The rotating wheel cuts, ignites and discharges small portions of the flint rod biased thereagainst away therefrom in a stream of sparks. An air stream directs the stream of sparks out as a special effects shower of sparks. One embodiment of this system propels the spark stream out through a venturi nozzle. By changing the gas stream fluid pressure and/or the clutch connect time and/or the flint rod biasing pressure and/or the clutch connect/disconnect interval timing, the size and characteristics of the shower of sparks can be accurately controlled and altered as desired.
