The Artful Life: Growing Crystals with a Bubble Rock

“What the heck is a Bubble Rock?”


It’s a geology experiment waiting to happen, and one heck of an affordable souvenir from the Ore Cart Rock Shop in Estes Park, Colorado! The Bubble Rock is a naturally ocurring Limestone mineral that is found in Western Utah. With proper conditions that are similar to a cave environment, it will grow its own crystals!


Here’s what you’ll need:

Bubble Rocks– if you can’t make it to Estes Park, you can order them online at The Rock Shed (scroll down the page- they are $5.00 each)

White Vinegar- no fancy stuff, just plain white distilled vinegar

A Clear Glass Container- a wide flower vase or bowl will work, you will want to make sure you can easily reach your hand around the rock to remove it once you have grown the crystals

A nice, safe place to place your container for up to 2 weeks, undisturbed- you will want to place it where you can easily view the progress of the growing crystals

The rest is very simple and easy!


Unwrap your rocks (it’s nice to have one for each “geologist”), and place it in your container.  Again, be sure to leave enough room around the edges so that you can easily pick up the rock once all of the crystals have grown- they will be very fragile!


Add enough white vinegar to just barely cover the top of the Bubble Rock. If you get a little too much, no big deal, it will just take a bit longer for the vinegar to evaporate and get the crystals started.


The vinegar causes a chemical reaction with the minerals in the rock.  Within a few days tiny white Aragonite crystals appear and gradually place themselves to form clusters of white blossoms.  Similar aragonite crystal formations occur in caves in the form of stalactites and “cave flowers” (anthodite) such as in Carlsbad Caverns.


After about two weeks, your rock will look like this!  Carefully extract it from your container and allow it to dry.   You will have a very special crystal keepsake to tell friends about!
