Ah. That's something I forget a lot - I'm one of these people with really
low skin resistance. Makes static electricity a pain (quite literally), and
means a few volts can make it up my arm if it wants to. Haven't dared try
it across the chest - almost killing myself with the mains when I was a lot
younger kinda killed my incentive to try zapping myself like that.

It wouldn't so much melt it as vaporise it and leave a thin layer of metal
around everything in the vicinity. Seen it done. Nice trick, if you
arrange to be a long way away at the time. CCTV helps.
