Ice cubes are small, solid pieces of frozen water, typically made by freezing water in a tray or mold. They are commonly used to cool beverages, such as soda, water, or cocktails, and can also be used in food preparation or preservation. Ice cubes can vary in size and shape, depending on the tray or machine used to create them. They are often made from clean drinking water, but can also be made from flavored liquids or juices for added taste. When added to drinks, ice cubes melt slowly, helping to maintain a cool temperature.
