Rubens Tube - fire music visualizer with flamethrowers

Ruben the Pyrotube is a Rubens Tube made from galv drainpipe, computer sound system and compressed air fittings. Runs off a standard BBQ gas bottle. Flame height changes due to the change in gas pressure inside the tube. The soundwaves played into the tube change the pressure and therefore the flames. Mine has two jet pilot lights, Left and Right speakers and a pair of electrically controlled flame throwers. Great fun to set up in front of my Decks at parties :) The song is Blackout Crew - Put A Donk On It
