Why not make a sand castle sand casting (tongue-twister!) with plaster? You would have to "unbuild" the castle as a shaped hole into the sand, upside down, instead of building it up, and pour plaster into it. If your students are young, the reversal thing would be a problem, but they sure would look cool and it looks like solid sand. They could stick their fingers into it or push wooden blocks and other objects into the wet sand, and get neat turrets and spikes and things that I think would be fun to see in reverse.

Subject: - Castles out of sand?
Still in school, but thinking about VBS..... does anybody know how to create sand castles (like you do at the beach) but then make or keep them permanently? What about mixing elmer's glue in with the water (but what a mess on their hands)? Ideas? A Google search lead me to stuff like plaques or using a sandcastle mold, but the building aspect would seem to be the most fun part for kids. The 'look' of sand castles can be so cool.
