2,500 Bunsen burners used to visualize audio in trippy way

Back in the days of Winamp, audio visualizers were pretty rad. Then someone figured out how to turn those trippy visualizers into a screensaver. Remember those? Those were pretty cool, but they're nothing compared to the Pyro Board.

Veritasium's Derek Muller hit up a team of physics and chemistry demonstrators in Denmark to check out their 2D version of the Rubens' Tube, and needless to say, it's pretty friggin' awesome.

For those who don't know, a Rubens' tube is basically a long pipe with tons of holes running from end to end on its top. The pipe is then filled with gas and a speaker or frequency generator attached to one end. Gas leaking through the holes are then lit up. When sound passes travels through the tube, the flames "dance" up and down, effectively creating a visualizer.

Instead of a tube, the Pyro Board is a 2D plane of 2,500 Bunsen burners. When lit up, it kinda looks like some kind of 8-bit sprite art.

"The pressure variations due to the sound waves affect the flow rate of flammable gas from the holes in the Pyro Board and therefore affect the height and colour of flames. This is interesting for visualizing standing wave patterns and simply awesome to watch when put to music."

After watching the video, you won't be able to go back to your digital music visualizer of choice. Because everything is better with fire. Everything.
