An ice cube tray is a kitchen gadget designed for freezing water into small, uniform cubes of ice. Typically made from materials like plastic, silicone, or stainless steel, these trays are designed with multiple compartments that hold liquid, allowing it to freeze into individual cubes. The classic design includes rows or grids of small wells, which makes it easy to pop out the frozen cubes once they have solidified. Some trays come with a lid to prevent spills and contamination, while others are flexible, allowing for easy removal of ice cubes. In addition to water, ice cube trays can also be used for freezing juices, herbs in oil, or baby food, offering versatility beyond just ice. They are often available in various sizes and designs, from standard rectangular trays to novelty shapes, and can be a practical, space-saving item in any freezer.
