Grow Your Crystal Geodes
The odds of stumbling upon a geode full of sparkling crystals in nature is practically zero—so it's a good thing you can grow one yourself, without even leaving the house. Mix up some crystal compound, close it up in the special crystal shell, then get ready for the hard part: waiting! Chemistry, geology, and patience come together to form a glinting, gleaming bed of crystals, so crack it open and see what you grew.
