What’s going on here?This magic rock is a naturally occurring mineral found in the Western United States. Calcium carbonate (CaCO3), the main component in limestone, reacts with the acid in white vinegar and releases carbon dioxide gas, which makes bubbles. The same geological process that makes these crystals also creates beautiful limestone formations in nature, such as the thermal basins of Yellowstone National Park and the underground rooms of Carlsbad Caverns. Your Growing Rock is an Aragonite Crystal. Made in the USA Show more
