I think the gas is escaping before I can press the ignitor, i'll try it a few more times to try and get the gas to work.

I don't really have the time to make stuff like this, I just got bored and started playing around.

I thought, as a first gun (and probably last...), I should make something simple, but original; a pill bottle, but smaller and easier to disguise. What I have done is do away with the pill bottle itself, block one end of a pen tube (the thin end) with some wax and stick the electrodes straight above...
