The MAGICFX® SUPERBLASTER is equipped with a CO2 powered woofer. CO2 is blown into the woofer through small holes. This creates a Venturi effect that continuously draws the confetti from the hopper, out of the woofer and into the air. The effect is accompanied by a strong hissing sound. If liquid CO2 is applied, a white plume of smoke will be visible. The CO2 supply is controlled by hand with the CO2 valve. To keep the effect going the operator must continuously fill the hopper with confetti.
