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.

      Very cool!

      Very nice demonstration. unfortuantly, we also used PVC our first attempt. the second was with an aluminum gutter pipe, which is working fabulously. do you have a membrane on the speaker end? we got much better results with one, but our speaker is not the same size as our tube either

      Somebody needs to introduce this man dubstep.

    • Teetoowowman December 18, 2011 at 10:07 pm

      I need to know this in order to proceed to my project.
      Is it necessary that we require a speaker for the frequencies? :/ what happens if we make some live music right next to it (for example a bit of drumming)?
      I need a reply asap despite how dumb my question sound.

    • twinrawk December 19, 2011 at 8:03 am

      I don’t really know. I do know you can get reactions at high enough sound pressures. I have been in clubs with big systems and not needed the speakers attached to see effects. But drums also do not produce very pure freqencies. You will likely see the flames move and jump. But it will be difficult to produce a sine curve with out pure frequencies and a speaker. With the right sound pressure and room I imagine you could. Report back what you find! be careful.

      @jorkeuh There is a very good post on the MAKE magazine site. I would google MAKE magazine and Ruben’s Tube you will find it. Or read all the comments I think there are tips below. Do not make one out of PVC. That was a dumb idea. It produces nasty fumes as it heats.

      Wouldnt the fire be more intense in the area where the air is compressd? Therefore more air is pushed out of the holes and raises the wall of fire?

    • mexicanbadass1 February 25, 2012 at 4:12 am
