I have been meaning to ask about this for a long time, also this may need to be
forwarded to a physics forum.

I once saw a demonstration of a flame of burning gas used as a device for sound
reproduction (Simply: A Speaker).

All I remember was the flame was passed through a ring at mid-flame, and possibly a contact at the base of the flame.

In the demo, all they did were simple tones, I think it could be used for more
complex sounds though.

Does anyone have any information on this?  I always though it would be a great
item for a party (outdoors!) and a great conversational piece.
