Break open a plain-looking rock to see if there are quartz crystals inside! You provide a hammer or rock pick and help for young kids. Geodes are formed when mineral deposits build up inside volcanic or sedimentary rock "bubbles." Grades K-12.
Note: Although not every geode contains crystals, they are still fun to break open and have interesting mineral deposits inside.
I didn't use a hammer so it was pretty hard to whack it open, but once I did...How amazing it was to see something so beautiful! I felt like I struck gold! I am very excited to add such a beautiful rock to my ever growing collection. Not only was this a fun project but I learned alot too. I recommend everyone buy one of these, not hard to do at these prices and I KNOW you will be satisfied. Happy Whacking!

These Crack-Open Geode's Kit are so cool. You never know what you'll find inside. When mine was cracked open, there was a cool crystal inside.
