Product Description

Just place this rock in vinegar and watch as natural white crystals grow out of it. Crystals will continue to grow for 1 - 3 weeks. Popcorn Rock is a naturally occurring mineral found at limited outcrops in the Great Basin of the Western U.S., whose amazing properties were first discovered by Utah geologist Richard D. M. Barnes in 1981. The same geologic processes that are at work creating the beautiful limestone formations that attract visitors from around the world to the thermal basins of Yellowstone National Park, and the underground rooms of Carlsbad Caverns, New Mexico are also able to produce a healthy crop of "popcorn crystals" for you when the Popcorn Rock is placed in white distilled vinegar and is left to dry out over a period of one to two weeks!
