What happens when you set music on fire? I present to you the Pyro Board. The evil geniuses at Fysikshow have taken the Rubens’ Tube and raised it to a whole new level. Using a flat metal plane with 2500 holes and lots of flammable gas, their invention shows how the varying pressures of sound waves will affect the flames. In short, the flames dance like 3d waveforms on a sound board. Fast http://angellsound.com/2014/04/pyro-board/
