We started with 1 mock rock and broke it apart. We found a whole bunch of minerals. We sorted them and put them in water. We poured out the water and put the minerals in a cup. Two days later we found that there were little tiny crystals in the cup. We washed them. The next day we looked at some crystals. The crystals were kosher salt, alum, and a few others. I loved the diffrent colors they are and their smooth texter.
