Popcorn Rock

Popcorn Rock is a naturally occurring mineral found at limited outcrops in the Great Basin of the Western United States. The amazing properties of these rocks were first discovered by Utah geologist Richard D. 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, if you follow the “Planting Tips” as provided.

Planting Tips: Put your rock in a clear glass bowl. Add just enough clear white distilled vinegar to cover the rock completely. Let the vinegar evaporate, and watch as popcorn-like aragonite crystals grow above the vinegar until it is gone. Once the rock is dry and hard, your crystals will last for years to come. Growing time is one to three weeks.

Warning: No you cannot eat it because it is rock silly. Eating rocks may lead to broken teeth.
