dazza ill be doing that some clear hose just above the chambers to so if i over fill it the water will run out and ill use those little plastic taps to shut it off so the gass wont come out i can put some windows in the chambers to view the bubles to , those plastic lenses from old cameras are usefull to and ive got them around to ,the top of the outlet pipes i can seal them and put plastic valve taps there to ,the same ones you use for the air hose to air stone in fish tanks , at least the gas will be more concentrated when comeing out of the outlet pipes and from there i can channel it through more plastic tube ,or just a rubber tube and to the brass nozel peace from my dead gas powerd soldering iron, allso im planing to try powering it from my high voltage photo flash capacitor charger as even with one capacitor is good and 2 in parralell much better so ill see if i can get more gas output at a faster rate if possible,
