Pyro board visualizes song’s beats with dancing flames

Idea based off Reuben’s Tube

What’s cool about the project below is the fact that not only do you get a bit of visual entertainment, you also get some learning in, too.

Per the science video blog Veritasium, the “Pyro Board” is a demonstration of what happens when sound waves travel through flammable gas set aflame.

It’s all based on a Rubens’ Tube, which is basically a long tube that’s able to illustrate stationary sound waves (a.k.a.: “standing waves”). In using some songs as the source of the sound waves, the pressure variations caused by the sound waves affect the flow rate of the aforementioned gas from the holes in the pyro board. This results in not on the height of the flame being adjusted per the beat, but the color too, making the board an awesome visual display of a fairly simple project.

The video runs six and a half minutes long because it goes into how everything works on a bit more of a granular level. If you just want to see some dancing flames, head to the three and a half minute mark.
