Full Answer

The rock candy experiment takes about a week to complete and demonstrates crystal growth in a super saturated solution. With adult supervision, students pour 1 cup of water into a pan and bring to a boil. Slowly add 2 to 3 cups of sugar, 1/4 cup at a time, allowing the sugar to dissolve until the water is completely saturated. An adult should pour the cooled solution into a tall glass or jar, and then suspend a wooden skewer or clean chopstick into the solution by placing a clothespin across the top of the jar. Crystals begin to grow in about 3 days, and the rock candy will be ready to enjoy by day seven.
