Things You'll Need
Instructions
Center a poker chip or bouncing putty (Silly Putty) in the bottom of a glass mixing bowl. This will allow you to transport your seed crystal without damaging its delicate structure later.
Mix 1/2 cup of salt with 1/2 cup of hot water in a small glass mixing bowl. Do not use boiling water as this will cause too rapid a growth rate for the crystal. Instead, use hot tap water. Stir the solution vigorously for one minute
Put the bowl with water and salt solution in the refrigerator immediately. Allow the solution to cool for three hours. You should have a growth of crystals throughout the bowl.
Grow a larger crystalline structure by transporting your seed (crystals on the poker chip) to another bowl and adding more salt and water solution. Repeat the above process until you are satisfied with the growth of the crystal.
