I'm looking for advice on what liquid(s) to use in a wave tank. It
will be about fifteen feet long, and serve as a visual anchor for a
small exhibit area. Visitors will control the strength and frequency
of the waves mechanically, but the tank will be sealed so we have
some freedom in choosing how to fill it.

Any suggestions? As usual, we're balancing the goals of looking great
(and sparking further, in-depth exploration) and keeping maintenance
simple.
