Behold the Pyro Board: an array of 2500 flames created by Sune Nielsen, a Masters student in physics at Aarhus University in Denmark.
How it Works: As you can observe in the video, the board is an extension of the device known as a Rubens’ Tube.
Pressure variations caused by sound waves affect the flow rate of flammable gas in each of the holes in the Pyro Board. This leads to variations in the height and color of the flames. The magic of the video happens around the 3:30 mark. Fire and music seem to be a very natural fit.
