assume you’re carrying static electricity and you touch something like a fire extinguisher or a can of spray on deodorant, what will happen.
You’ll see a spark if the lighting conditions are right. Other than that, nothing. The charge stays on the surface of the tank.
Unless you’re capable of holding an enormous charge, that is. However, that’s probably unlikely.
The amount of charge shouldn’t matter. In theory, at least, the tank forms a perfect Faraday cage, which keeps the charge on the outer surface of the tank. If the tank isn’t grounded, it can only hold so much charge itself, in any case.
Even if somehow the “spark” made it into the contents of the canister, nothing would happen, unless the contents included something flammable and an oxidation source – a rare combo on pressurized containers, especially those for household use.
If you did find this lethal combo, and the cannister was somehow built to then allow the charge to arc within, THEN blammo.
I think you were interested in the blammo part :dubious:
