We're making sand sculptures, starting with ocean critters. Last night, we made the dough. Monkey almost never will get gooey, and he had a slow start this time too. But before he was done he told me, "This is fun. We should do this again."
If you decide to do something similar, I suggest cleanup with a hose. This is really messy, gums up the sink, and Andy tells me the sand will get caught in the u-bend gas traps under the sink.
