Sorry I had a brain fart and forgot the technical term for it. But I'm trying to get the pressure to control the output of each of the flame spouts (which aren't working well either). I need help because all I can get it to do is explode inside. -_- Note: I also don't know how much gas should be inside or a method of providing the right   amount. So it's currently empty. I did come up with an efficient ignition system though. (tesla coils) :)

IT'S NOT A BARBEQUE! o\_/o It's those things you use to see audio waveforms in the flames. *googles it* A Rubens Tube.
