I just tried LEDs in a jar of salt water.  The LEDs would not light up.
However, I think the current was not high enough.  I probably should use
small NE2 style neon bulbs for greater sensitivity.  If the current is
spread uniformaly throughtout the water column, the current to each bulb
may be very low.  Or the water could be acting as sort of a faraday cage
although that "should" not be the case.
	Perhaps there is some simple indicator that could be added to the water to
sense the current flow?  Of course if one had a really big coil you could
use a snowman and just see were the ice melts... perhaps frozen salt water
would be good to try?

BTW - If anyone it trying stuff like this, be very careful of the water
around high voltage.  I, of course, was far back from this experiment!
