I found an even more interesting solution to use than plain water:
Well-used photographic fixer.  Photographic fixer works by removing the
light-sensitive silver from the paper, so the silver compound remains
in the fixer bath.  If you use fixer, you will discover that one of your
terminals (the anode, I think) will turn silver colored.  You can actually
peel off the flakes of silver that form on the terminal.  (Well, when you're
in high school, these things are pretty neat.)
