It could certainly be a combustible mixture in the tube, but the holes act like a Davey lamp ...sorry, you cannot view external links. To see them, please
REGISTER or LOGINAh yes. I understand the Davey Lamp principle, but then again, Davey didn't have a honking big loudspeaker in his lamp either . A safety valve would be good insurance.My brother had a Hillman Imp. One damp morning it would not start. My brother is not among the most technically aware, so he kept on cranking the starter in the hope that, by some miracle, the fuel would ignite.Evidently there was no problem with the carburettor because it did exactly what it was supposed to do and mixed the fuel and air in ideal proportions for combustion. Unfortunately this mixture was being pumped out of the engine and into the exhaust system in a sufficient quantity to completely fill the silencer.Eventually, my brother got the result he desired. Ignition! There was an extremely loud bang and the silencer was split wide open from end to end. The silencer was also immediately de-coked and all the carbon deposits spewed forth as flaming embers in the explosion.Fortunately no one was injured, but it certainly woke my brother up. I think he had to have a change of trousers.
They register people trained to do gas installations. I think it stands for something-or-other of registered gas installers, but I'm not sure about that....sorry, you cannot view external links. To see them, please

I am in the process of making a rubens tube for my physics class and having some difficulty. After lighting the tube I will only recieve a small blue flame instead of a larger orange flame. Also it won;t stay lit. It will go out almost immediately after lighting. Any help or suggestions would be much appreciated.
What would the optimum diameter for the tube be ? As this could cause a problem if copper were to be used and what distance did you put between your holes ? Thanks
I used 1mm holes at a 5mm spacing. I am not sure of optimum diameter. I think for a 1800mm tube like mine more the 50mm diameter is great for higher order modes, but the fundamental doesn't work quite so well. I also had a test tube which was only 20cm long which would only do fundamental and first harmonic, I think because the cross section was larger than the second harmonic, so complicated 3D standing waves started happening.
