Two party activities in one…first go on a hunt to find these homemade treasure-filled stones and then the kids can enjoy breaking them open to reveal the treasure inside.
A homemade clay recipe is used to make the stones, which keeps party costs down and you can include this activity in a variety of party themes. When a craft is inexpensive and versatile, it’s a party hit in my book!
You may need to double or triple the recipe for large parties.
- 1 cup used coffee grounds
- 1/4 cup sand or cornmeal
- 1/2 cup salt
- 1 cup flour or more
- 1 cup water and cold coffee combined
- Parchment paper
- Mixing bowl
- To make treasure or fossil stones, you’ll need small objects like beads, polished stones or coins.
- Variation: Add glitter or food color to make fairy treasure stones.
Before the Party:
- Combine the coffee grounds, flour, salt, sand/corneal and stir.
- Slowly add water and coffee and knead until you have a dough consistency.
- Shape the dough into balls.
- Make a hole in the ball big enough for a treasure or fossil.
- Press the “treasure” into the hole, pinching and adding more dough until the treasure is completely covered by dough.
- Air dry for 2-3 days or bake in the oven the night before the party on a cookie sheet at 150ºF for about 15-20 minutes.
- Test one of the stones by breaking it before the party.
- Hide the stones in a sandbox for a dinosaur digging activity. For a pirate fairy or garden party hide the stones around the party area before the kids arrive.
If you are using the oven-dry method do not use heat sensitive items in the stone. The best object tend to be glass beads, polished rocks and shells.
- Children will dig to or hunt to find a treasure stone.
- Break open the stone with kid-sized hammer to reveal the hidden treasure inside.
