Popcorn Rock

SKU: 400001799499

Popcorn Rock is an excellent tool for teaching chemistry and/or geology... or, for just plain fun. Submerge this limestone rock in white distilled vinegar and watch as an aragonite crystal garden grows over the next few weeks. Popcorn Rock makes a great long term educational project for the classroom or those aspiring young geologists at home. Shapes of the rocks vary. Each package has one medium sized rock. Made millions of years ago in Utah.
