The Pyro Board mixes sound and flame for a stunning visual display


Graduate student in physics and member of the Physics Show at Aarhus University, Denmark, Sune Nielsen has taken the principles behind the Rubens’ Tube  and “created what he calls the Pyro Board — an audio wave visualizer that uses flames to show the varying frequencies of sound.

Nielsen’s creation consists of a flat board drilled with 2,500 holes through which gas is emitted at a controlled rate. When specific audio frequencies are applied the air near the holes vibrate, which in turn reacts with the flow of gas creating corresponding bursts of flame.
