How Do You Make A Geode Of Blue Copper Sulfate Crystals?
Geodes are a type of rock containing crystals. Normally, millions of years are required for flowing water and minerals to deposit crystals. You can make your own ‘geode’ in only a few days. Grow beautiful translucent blue crystals of copper sulfate pentahydrate inside an egg shell to make your own geode.Difficulty: AverageTime Required: 2-3 daysHere’s How: • First, you need to prepare the eggshell. A natural geode forms inside a mineral. For this project, the mineral is the calcium carbonate of an eggshell. Carefully crack open an egg, discard the egg, and keep the shell. Clean the egg from the shell. Try for a clean break, to create two halves of the shell, or you may wish to just remove the top of the shell, for a more ball-shaped geode. • In a separate container, add copper sulfate to 1/4 cup of hot water. The amount of copper sulfate isn’t exact. You want to stir copper sulfate into the water until no more will dissolve. More is not better! It should take a few pinches of solid mat
