Digging for fossils.

Home made "fossils" are fun, cheap, and easy.

1. Purchase (at the dollar store) those cheap plastic dinosaurs and lizards.
2. Make up a batch of salt dough.
3. Mix a cup full of dirt (from outside, don't buy dirt.) into the dough.
4. Wrap balls of dough mixture around each lizard/dinosaur.
5. Let dry.
6. Give them to the kids with a dull butter knife and tell them to find the animal inside.
