RSSRuben's Tube - Sound visualization... with FIRE!
Here's a really neat way to see sound waves... With fire! I think if I ever make a fireplace, it'll have something like this. Twinrawk writes - "The classic physics experiment involving sound, a tube of propane and fire. Created for Flash Forward 2006, but useful in any case where you are not allowed to have fire. I push through the tube 449 Hz then higher frequencies, then some jazz and then some rock. This is real life sound visualization." [via] - Link.

On the rock song... Is it playing off tape or something? Because it leaves rather nasty gaps in the visualization.
The gap is caused because there is a standing wave there. Based on the length from the speaker to the large gap, I suspect there is a lot of musical information at about 175hz in the song.
In open air a 175hz wavelength is about 6.5 feet. So we should see a standing wave at .5*wl or 3.25 feet.
