Materials Needed:
- 1 cup flour
- 1 cup used coffee grinds
- 1/2 cup salt
- 1/4 cup sand
- 1 cup water
Instructions:
Mix all dry ingredients together. Slowly add the water to make a stiff dough; you might end up using only half the water - add it slowly or your dough will be too runny!!
Knead on a floured surface until fairly smooth. Break the dough into desired rock sizes. Hide toys and surprises in the center of a ball of dough. Set in a safe place until totally dry. Atleast 3 - 4 days.
Once it is dry, the dough will look and feel like a rock. You can carefully break open the home-made rocks with a hammer to reveal the hidden treasures inside.
