I’ve seen that before but it’s still pretty wicked.

Not the same at all, but just as potentially dangerous…
Wow. That would be sexy to build and put somewhere in my apartment. Gotta get the fire insuance in place first.
I don’t’ think that is a spectral graph. It is more a standing waveform analysis, more similar to a oscilloscope…
I loved this, thanks for posting! When I watched other linked videos to this, the Flute one was my favorite. I wonder if it looked so awesome because she used a much larger tube, better hole size or a better quality gas? … and how do you keep the propane from burning back to the tank and exploding?
