I had a longer video, but either the size was too large, or it had somehow gotten corrupted during the transfer. It doesn't seem like the above attachments are playing, though, so perhaps something has gone wrong with the upload. 

In any case though, it was a very interesting setup with a very interesting concept behind it - I'd never really thought about how sound might affect the movement of flames - I suppose it makes sense, since sound is the vibration of air, and of course flames are affected by the movement of air particles. I just hadn't realised to what extent. The low frequency sounds coming from the tubes made me wonder, how the flames would behave with shriller sounds? Perhaps the vibrations would be too weak to cause much change of note.. or maybe just unpleasant to the ears!
