Treasure Stones
Total Time afternoon or evening Ages all-ages

Here's a fun activity that's perfect for your next summer cookout or family reunion: an outdoor search for special homemade rocks that you crack open to reveal pretty jewels and trinkets.

What you'll need

  • Plastic jewels and small trinkets
  • Glitter or sequins
  • Tissue paper
  • Aluminum foil
  • Plaster of Paris
  • Disposable container
  • Plastic spoon
  • Waxed paper
  • Acrylic paints
  • Paintbrushes
  • Pair of plastic gloves

How to make it

  1. To make each rock, tightly wrap a jewel and glitter or sequins in a small piece of tissue paper, then tightly wrap the whole thing in aluminum foil. Repeat with the remaining treasures.

  2. Prepare the plaster of Paris in the disposable container according to the package directions. When the plaster is ready (it should be about as thick as a milkshake), one at a time, drop in a foil packet, swirl it with the plastic spoon until it is evenly coated, then spoon it onto a sheet of waxed paper and allow it to dry. To clean up any leftover plaster, let it harden in the container, then dispose of it in the trash.

  3. When the rocks have dried (about a half hour), coat each one with acrylic paint. (Tip: Wear plastic gloves so you can handle the rocks as you paint them.) For a particularly realistic effect, apply a darker shade first, then dab on a lighter color with a paper towel or cotton ball.

  4. Treasure Stones

    Once the paint has dried, hide the treasures around the yard, then invite your kids to come snoop them out. After they've collected them all, show the gang how to crack the stones (squeezing or tapping them on the ground should do it) and remove the plaster, foil, and paper layers to discover what's inside.
