Wow your kids by showing them how to make these magic treasure rocks. Not only will they enjoy getting their hands dirty when forming the rocks, but they will be excited and surprised to see their creations fizz and foam in vinegar to reveal secret treasures!
Materials Needed:
- Baking soda
- Water
- Vinegar
- Small treasures
- Glitter
- Food coloring
Step One: Pour some baking soda in a bowl and add a tablespoon of water at a time to form a thick, moldable paste.
Step Two: Divide the baking soda mixture up into smaller bowls and add different colors of food coloring. You also can add glitter at this point, if desired. To create rainbow rocks, mix a few different colors together for a marbled effect.
Step Three: Take a few tablespoons of the mixture and flatten it out in your hand. Put a small treasure, such as a bead, coin or toy, into center. Add more of the rock mixture on top to enclose the treasure.
Step Four: Put the rocks on a baking sheet and let them dry overnight or bake in a 350 degree oven for about 20 minutes or until dry.
Step Five: To uncover the treasures, place the rocks in a bowl and cover with vinegar. The magic rocks will fizz and foam until they dissolve to reveal the hidden treasure!
