What you'll need:
Background:
Bubble rock in a natural mineral found in Utah. Its beautiful white crystals are the result of a reaction with vinegar. Similar geological reactions have created the fascinating formations that we see within caves throughout the world.
Procedure:
Once your rock is completely dry, your crystals will become more stable. Crystals are fragile. Handle with care and enjoy!
