We love gnarly looking home brew experiments that appear to be incredibly dangerous, and few look more dangerous than this homemade sound to flame generator built by Rusty Oliver in his aptly named HazardFactory.
Oliver's flaming display uses two parallel Rubens tubes, which are normally used to create a visual display of sonic standing waves. Propane is pumped into the tube, which exits through a row of holes running the length of the tube. Set the escaping gas on fire, and you have what looks like a high-tech Yule log. The final element is a speaker, which modulates the gas in the tube resulting in a visual display of the acoustic wave patterns.
That's pretty cool by itself, but Oliver wanted more awesomeness, so he set up two of the tubes as a parallel pair, then ran high voltage between them to further modulate the flames. The principle is the same as that high voltage fire fighting system we saw recently.
The resulting display makes your average light show look kind of tame, just try not to electrocute yourself or burn your house down.
