Inside this box you will find 10 ordinary-looking rocks. But put one of the geodes in a bag (or an old sock), put on some safely glasses, and smack the rock with a hammer. Once it's cracked open, you will find the geode's inner crystal beauty. Geodes are found in many parts of the world; these come from Mexico. Many of the geodes in this package will have crystals inside.

Adult supervision recommended for children under 10.
