What You Need:
- 1/2 cup coffee grounds (used or instant)
- 1/2 cup sand
- 1/2 cup salt
- 1 cup flour
- 1 cup water
First, find small, non-plastic objects that you want as treasure for inside your rocks. We let the kids go around the house and pick out what "treasures" they thought Dad would like: glass marbles, a jingle bell, "gold" buttons, coins, and fake diamonds were what caught their eye! They even decided at the last minute to put leprechaun gold in one!
Now you are ready to make your rocks! Preheat your oven to 250 and mix your dry ingredients together.
Then add the water a little bit at a time until you get a play dough-like consistency.
Once your dough is just right, divide it up depending on how many rocks you want. Then flatten the divided parts...
...and place your "treasures" inside.
Then fold the dough around the "treasures" sealing them up. Mold your dough into the shape of rocks.
Place your rocks on a cookie sheet, pop them in the oven, and bake for 15 minutes. Once the time is up, leave your rocks in overnight to finish drying. We found that ours were still a little underdone on the bottoms, so we flipped them over and popped them back in for some more cooking time. And there you have it: Homemade Treasure Rocks! Do they look real or what??
Now the fun part: breaking them! Dad had a great time breaking open the Treasure Rocks with the boys and seeing what wonderful things they had hidden! No, a rock hammer is not necessary, just more fun!
This was a fun project for the whole family, as kids of all ages could help make (and break!) them!
