The science of acoustics is a valid branch of physics. It was amazing to me that one of my physics profs was studying acoustics in a candle flame in the 60s. One can actually do cutting edge physics, even lab physics on beer money.

It was amazing to me that one of my physics profs was studying acoustics in a candle flame in the 60s.

A decade or two ago some company actually made speakers for home stereos which produced sound by manipulating flames, although I don't remember the company or product name.

I couldn't find it Googling, but I did turn up this related project, which includes two different video clips of flame being used to reproduce audio: Voice of Fire project.
