Rock Candy

"Rock candy is a simple sugar candy that can double as a science experiment. The process can take up to a week, but it’s fun to watch the sugar crystals growing over time. Note that the exact quantity of sugar syrup you will use depends on the size of the jar you have. If you want to make several pieces of rock candy, use multiple jars and skewers, and double or triple the sugar syrup solution as necessary.
