To grow crystals, first boil water and mix it with the crystal-growing powder in a mixing bowl until dissolved. Pour the solution into a crystal-growing chamber and let it cool for 15 minutes. Drop the seed crystal rock into the chamber. Leave the experiment undisturbed for 7-10 days. Once crystals have grown, carefully remove the remaining water and take out your crystal.
