The video introduces geodes, explaining that they are rocks with crystals inside. It describes how geodes form over thousands or millions of years through mineral deposits in empty spaces within rocks. The video provides instructions on how to safely open geodes using a hammer and safety glasses, and demonstrates breaking open geodes to reveal the crystals inside. The size of the crystals indicates the age of the geode.
