Ruben's Tube

Uploaded by twinrawk on Sep 15, 2006
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.

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.

@Teetoowowman 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.

Can i Ask you how you Make this?
In Steps?

@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.

How did you ensure that the same rate of gas came out of all the holes?
dirtymussh 4 months ago
@dirtymussh by ensuring the tube is level and the holes are the same size. Propane is heavier than air. So if the tube is level the point of entry is less important as it falls to the bottom and propigates upward evenly. However it does still have a tendency to favor the side the gas is entering. Also the flow rate of the gas is very low. Google for the make magazine build instructions. Do not use PVC. That was stupid.
