Description
 
Take this rock and cover it with white vinegar to watch it grow a popcorn-like aragonite crystal as the vinegar evaporates! Once the vinegar evaporates the crystals harden and will last for years. Growing time is one to three weeks.

Popcorn rock is a naturally occurring mineral found at limited outcrops in the Great Basin of the Western US, whose amazing properties 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.
