Transcript:How to Grow Crystals

Well, hello. Im Ben Roy from gosciencezone.com, for About.com, and today I am going to show you how to make crystals.

Materials to Make Crystals

To make crystals, you will to make a saturated solution. Do this by adding a crystal solute like, sugar, salt, alum, into a water solution. Starting your crystals off in a saturated solution is best because you want to maximize the chances for the solute particles to come together, and later form a nucleus. This grows into a crystal. If your solution isn't saturated enough, it could later make your crystals dissolve in water. 

If your crystal solute is having trouble dissolving, heat it on the stove for a few minutes and stir.

How to Make a Crystal Garden or Geode

To grow a crystal garden or geode you'll need to have a substrate which is a rock, brick, cork; pour your saturated solution over your substrate.

Next place a paper towel over your setup go block dust from touch it. This also allows the liquid to evaporate.

How to Grow Crystals in a Glass

You can also take a pencil, and attach a piece of string to it. Then add a paper clip or key ring the end of the string. Set it down in the glass of saturated solution, and cover it. Make sure the paper clip is not touching the bottom of the glass.

You should start to see crystals after a day.

If crystals begin to form on the glass, remove the pencil into a different glass of saturated solution to continue growing.
