Crystals for Geology & Science Lessons

Study crystals with some surprising properties, or grow your own! Sometimes called "Popcorn Rocks", gray Dolomite samples grow beautiful white Aragonite crystals when placed in a small bowl of white vinegar. The Rock Candy Crystal Growing Experiment Kit is a scientific experiment you can eat! Crystals grow to full size in just 7 days! Bismuth is one of the few materials that have a greater density as a liquid than as a solid. The crystals that form from melted and cooled bismuth are beautiful, and all completely unique.
