While some candy is sugar-free, most candy consumed during Halloween has some form of sugar. The production of candy can become quite the art form. Different ways of mixing and cooling the sugar allow for different types of crystals to form. For example, large crystals can be made for rock candy versus very small crystals as found in fudge. Watching these confections being made is a truly amazing experience! Have fun exploring the science behind candy with these sweet activities!
