Make your own Rock Candy! Dissolve 3 cups sugar into 1 cup of water that has been heated over medium heat. Pour evenly into 4 glass jars, or 2 if you want longer sticks of candy. Fix your candy sticks to a pencil and hang over the middle of your solution of sugar, add food coloring and/or flavoring. Cover with paper towel and leave undisturbed for 7 days and the sugar will climb up the sticks making rock candy!
