I know its the vapor not the gas itself, I know more about what I'm doing with fuel than I may sound like, thats why I knew I could do the demonstration. Like I said, I admit that when I was 16 and I smoked analogs pumping gas, it was stupid, my point only was, that using a pv or a cell phone while pumping gas into your car isn't as big a deal as some make it to be, we are just raised in a scared paranoid society, the 4 volts your cell phone makes isn't enough to even make any type of spark, the natural resistance of air is too high, unless maybe you pulsed it
through a bad ... step up coil like the way camera flashes work, but then you are just being stupid
I do understand your point about making the habit look bad, never thought of it like that.
But all that aside, I guess I will keep my little amusements to myself from now on so as not to be attacked
