Simple Crystals Kit
Bag of Knowledge
by DuneCraft

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! Comes with 1 color tablet, but you can also use food coloring for stunning colored crystals. The Simple Crystal is safe for ages 4 and up, non-toxic, and environmentally friendly.

Ages 4 and up.
