Bubble rock is a carbonate rock undergoes a chemical reaction when immersed in a weak acid, such as vinegar. This reaction causes some of the rock to dissolve and recrystallize, growing beautiful white crystals on top of the specimen.

This pack includes two, 2-3" bubble rocks (gray limestone), as well as instructions for performing the experiment.
Required materials (NOT included): Distilled white vinegar, and a transparent glass container.

The process is simple - place rock in a transparent glass container, and place the rock in the white distilled vinegar. Leave a small portion of the rock unsubmerged. Leave the rock in the vinegar, and within 1-2 weeks, crystals will begin to grow.

An exciting experiment to conduct with your students in the classroom or enjoy at home!
