Isolated as I am out here in the Indies where the rum is brewed, I wonder
if I could ask for some exhibit help?  Namely we are in the process of
scripting an exhibit titled "Wind, Tides, Currents, Trash."  In various
science museums I have seen visitor-activated wave machines--basically a
prop that shows that a wave is not moving water, but moving energy. I want
one big enough so that we could illustrate the break when the wave pulse
encounters the bottom.  I would prefer to fabricate our own, since we have
a pretty sophisticated exhibits shop inhouse.  Anyone seen one of these and
know where we could find plans?
