True indeed, but doesn't salt water conduct quite a bit better than fresh water?

I would guess, but it would probably depend on what minerals are present in the fresh water.

I'd imagine it would travel in a half-sphere shape through the water.

Stupid alcohol. ;)

I had attempted an answer but then found this :)

Very soft waters have a specific resistance of about 50,000 ohms; average fresh water about 6,000, and hard water about 3,000 ohms. Average sea water has a resistance of only 18 ohms.

Nice link. I'd no idea sea water was so conductive.

Oh yes it does. Not well, but it does. 10^-14 disassociation into OH- and H+ is enough for it to conduct, albeit only a tiny bit.

Our teachers lied to us
I googled around and found the same thing. I wonder what else I accept as fact that I was taught in school. :(
