This is a fun and easy activity to do with scientists of all ages! It only takes about 10 minutes to set up and then you observe and record the results over 1-2 weeks.
What you'll need:
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.
Once your rock is completely dry, your crystals will become more stable. Crystals are fragile. Handle with care and enjoy!
