Break open a plain-looking rock to see if there are quartz crystals inside! Use a hammer or rock pick to see what's inside this medium-sized crack-open geode, and be sure to assist young kids wanting to participate! Geodes are formed when mineral deposits build up inside volcanic or sedimentary rock "bubbles." Their typical size is 1.5" to 1.75".
Note: Although not every crack-open geode contains crystals, they are still fun to break open and have interesting mineral deposits inside.
Warning: CHOKING HAZARD - Small parts. Not for children under 3 years.
