Rock Candy

When you make rock candy, you can see the shape of sugar crystals on a giant scale. The key is giving them lots of time (about 7 days) to grow. As the water evaporates, sugar crystals form on the string or stick, and the shapes that they form reflect the shape of individual sugar crystals In the field of crystallography, these are called monoclinic crystals. Their shape is determined by the way the individual sugar molecules fit together.
