So yeah, long story short, I built a flame tube (Ruben's Tube)

I uploaded 6 of the best photos, but I will be taking more later. Was really fun to build and especially fun to play with.

That is uber cool. I didn't know that frequencies had an effect like that.

Yeah, it creates high and low pressure points where the nodes and antinodes are in the pipe.

OMGumby!:neckbeard:

Hehe, applied science is always fun. Maybe you can sell those for stage shows, if you can produce a bit longer flames ;).

Dude. Youtube. NOW. That is awesome.

Does it merely push oxygen into standing flames, making them momentarily burn brighter?

The sound waves create low and high pressure points which in turn is visible from the propane burning. It doesn't look like that for just a second, it actually stays like that as long as the speaker is making noise.

I will take some video hopefully on Monday and upload it when I get a chance. Technically I have a 3 second clip, but its not much.

For those that don't understand exactly how it works, this explains it fairly well:

that's awesome

I didn't really get any good videos or photos after the first day because it is degrading. We plan to build a metal one, but that will be later.

Here is a video I got on the second day, atleast it shows what it can do.

That's pretty slick.
