Exploring Crystallization Through Rock Candy

The video introduces candy-making as a chemistry-based hobby, focusing on making rock candy. It explains the materials needed, the process of dissolving sugar in water, and setting up the experiment. The video details the crystallization process, where sugar crystals form on a chopstick, creating rock candy. It concludes with suggestions for observations and encourages viewers to try the project with a grown-up helper.
