Sometimes called 'Popcorn Rocks', these gray Dolomite samples grow dazzling, white Aragonite crystals when placed in a small amount of white vinegar. This experiment is a must for any classroom studying rocks, minerals, crystals, or geology. Each set comes with complete instructions. You simply supply some small plastic bowls and the white vinegar (available at any supermarket). The crystal growing takes approximately one week depending on the temperature and humidity levels in your classroom. You and your students will be amazed!
