What is a Geode?
Geodes are formed from fluids which crystallize in cavities within a rounded rock or nodule. Geodes are found in many parts of the world. The geodes contained in this set are from Mexico; 90% of them have hollow centers lined with crystals. Break open yours and look for the hidden crystals!
How to Break Open Your Geodes
Put the geode in a bag or sock. Hit it firmly with a hammer, aiming for the center - safety glasses and adult supervision are recommended.
