For a real show, try making a cast of an underwater print. Carefully set
a ring around the print (I use a metal rather than cardboard one). Then
sift plaster of paris into the ring. Some will miss as it floats down
through the water but that doesn't matter as long as you get enough in
the ring to fill the track and provide a base. It's been a while since
I did one but I think it set up in less than an hour. It's a real Oh-wow!
for the kids (and a lot of parents).
