- Age Guideline: 3 Years and Up
- Time Required: 30 minutes (Does not include drying time)
The above age and time guidelines are estimates. This project can be modified to suit other ages and may take more or less time depending on your circumstances.
- 1 cup flour
- 1 cup used coffee grinds
- 1/2 cup salt
- 1/4 cup sand
- 1 cup water
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. At least 3 - 4 days.
Once it is dry, the dough will look and feel like a rock. You can carefully break open the homemade rocks with a hammer to reveal the hidden treasures inside.
