Create your own geode as you learn about crystals and super saturated solutions. Geodes start out as hollows. The outer shell hardens into rock. Inside the hollow water drips and leaves behind mineral deposits that turn into crystals. When a geode is cracked open, what you see is hundreds of thousands of years of drip, drip, drip. Now you can build your own geode in a fraction of the time!
