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. This growing rock is an Aragonite Crystal.  Not intended for kids under the age of 5 years of age.
