Cover the jar with plastic wrap and set aside to cool.Ĭrystals should begin to form on the string in a few hours, but they may take up to 10 days to fully form.Pour the solution into the canning jar and replace the pencil across the mouth with the string submerged into the jar.Carefully dip the string in the solution and then roll it in dry granulated sugar.Let the solution cool for about five minutes.Remove the pan from the heat and add food coloring (darker colors work better).

Wrap the string around the pencil a few times and hold it in place with a piece of tape. If you are looking for more fun ways to create crystals, there are many great experiments online.
