Flames that serve as speakers! Imagine a 7.1 set with these! (But perhaps not as comfortable in the summer...)

I've done this with a candle flame (and a propane torch), a step up transformer and a public address amplifier. I think it was in 1966. Doesn't have any bass response, mostly treble and it's never very loud no matter how much power is applied. Because I didn't have a DC power supply to bias it, the sound was distorted too.
