Price: $6.99 Sale Price: $4.95 each Item No: 10852 In Stock: 34 units in stock Ships same business day. Quantity:   Grow your own Aragonite crystal in just a few weeks-safely! These Magic Rocks form crystals naturally by adding a small amount of white distilled vinegar. The calcium carbonate in the rocks reacts with the acid in white vinegar to release carbon dioxide gas (you can even see the gas bubbles rising from the rock!) and produces a natural white crystal that will last for years! Add food coloring for stunning colored crystals. How To Grow: Put your Magic Rocks in a clear glass or plastic bowl. Add just enough white distilled vinegar (available at grocery stores) to cover the rocks. Magic Rocks will begin to bubble when vinegar is added! Watch your crystals grow on your Magic Rock above the vinegar as it evaporates. It's that easy! That's why we call it The World's Simplest Crystal Growing time is one to three weeks. Crystals are fragile. Handle with Care. Box Size: 8.50in (21.59cm) x 5.50in (13.97cm) x 0.50in (1.27cm) Recommended for ages 5 and older.
