Re: I may have unbelievable news, but salt water is actually a very good conductor
The problem with a stream of piss is surface tension as it rapidly turns from a stream to droplets. I recall there was a Mythbusters episode about pissing on an electric fence or the third rail or some other charged whatsit.
As for it drying out couldn't one just leave the loose ends in a bit of fluid and have it act as wick?
