Crack your own Geo
A Geode is a type of rock formation that occurs when a pocket of air or gas is seized and forms a cavity in a sedimentary rock. Split them open to reveal the beauty of the sparkling quartz crystals inside. As the old saying goes, “it’s what’s on the inside that counts”.
How to break it: Put the geode inside a paper bag or an old sock, place it on a protected flat surface and hit it softly at first then gradually build up the force until the geode splits.
