My little guy has been studying dinosaurs in school for the past few weeks, so we made up a bunch of treasure stones with dinosaurs hidden inside for his class. Each of the kids got to take a stone home from school and unearth the dinosaur.
Evan loved breaking his apart.
2 cups flour
1 cup coffee grounds
1/2 cup salt
1/4 cup sand
1/2 cup water
Mix it all up, shape into a ball and insert a dinosaur (or other treasure). I let mine dry for several days, but you can also put them in the oven on low for a few hours. I had to make five batches of dough to get 20 treasure stones, but I made my stones a little big because of the dinosaurs I bought.
Also, I’m not a coffee drinker, so I called up one of my seven local Starbucks and asked if I could have some used coffee grounds. They were more than happy to share them with me. The stones did smell a bit like coffee, but Evan didn’t seem to mind.
