step-1Mix a few drops of food coloring with ¼ cup water. Place 1 cup baking soda in a large mixing bowl. Slowly add the colored water, mixing with your fingers, until you get a mixture that is damp and moldable, but not too wet.

step-2Add a few gems and coins to a small clump of rock mixture, then pack more mixture around the treasures until they are completely hidden. Place rock into the well of a muffin dish. Sprinkle with glitter and let dry overnight.

step-3Repeat steps 1 & 2 until you make as many rocks as needed.

step-4Download the tag and instruction templates and print onto cardstock. Cut out each along the gray lines and punch a hole in the tags.

step-5When the rocks are dry, place each in a cellophane bag with instructions and tie with baker’s twine. Tie a “You rock!” tag on each.
