Description
Grow your own crystal! Everything you need is included in the set.
Since the dawn of time, humans have had a special relationship with things that sparkle. Crystals are rich in detail, they are beautiful, and the key to understanding more in many branches of natural science. Now you can learn about the beauty and mystery of crystals by growing them on your own kitchen counter!
All you have to do is add boiling water to the beaker, dissolve the powder with the stirring stick, and then watch beautiful crystals slowly form over the next few days.
That's how it works
When you add the powder to warm water, the crystals dissolve. The liquid is called a saturated solution because it is not possible to stir in more powder. When the solution then cools, it is no longer able to hold all the salt. It therefore precipitates out, forming beautiful, angular crystals.
