Remove the pencil and yarn once you verify that the yarn reaches the bottom of the jar.Boil 1 cup water, remove from heat, and add up to 3 cups sugar, 1 tablespoon at a time. Stir as the sugar dissolves, and continue this until no more sugar can dissolve.Pour the sugar solution into the glass cup or jar.Place the pencil and string across the top of the jar and make certain the end of the yarn is in the sugar solution.Leave the crystal setup alone. Cover the top of the cup or jar with thin gauze or paper if you like, to prevent dust or bugs from getting into the solution.Check your crystal project within 24 hours; crystals should be forming.Leave the crystals alone for a week. By the end of a week (sometimes up to 10 days) the crystals should have crept up the string and be fully formed.
