I'm doing a dinosaur co-op and I want the kids to be able to excavate some dinosaur bones. I was hoping to make some shoe box (or smaller) sized bricks with plastic dinosaur bones burried in them. I'd like it to have a consistency of packed earth like a "real" dig site might.
I recall reading about mixing sand, plaster of paris and some flour/baking soda and water...I think... but I can't find it and I can't remember the exact proportions.
Can anyone help? Has anyone tried this kind of thing?
Thanks in advance
