This is a video tutorial in the Food category where you are going to learn how to make rock candy in your spare time. For this you will need 4 cups sugar, 2 cups water, small saucepan, wooden spoon, candy thermometer, glass jar, measuring cup, cotton string, a weight to hang on the string, waxed paper and a pencil. Boil water in the saucepan and dissolve the sugar in it. Pour the solution in to the jar. Tie the weight to one end of the string and tie the other end to the middle of the pencil. The string should be about two-thirds as long as the jar is deep. Dip the string into the sugar solution, remove it, lay it on waxed paper and let it dry for a few days. Gently suspend the prepared string in the solution and let sit for several days. You can check each day to see how much your crystals have grown. Don't touch the jar until the experiment is finished. It usually takes about seven days.
