Ice trays are simple kitchen tools used to make ice cubes. They are usually made of plastic or silicone and come in various shapes and sizes. To use an ice tray, you fill it with water and place it in the freezer. After a few hours, the water freezes into solid ice cubes, which can be easily removed for use in drinks or other purposes. Most ice trays have a flexible design, allowing you to twist or bend them to release the ice cubes easily. Some modern versions even have lids to prevent spills and keep the water clean. Ice trays are a convenient way to enjoy cold beverages, especially during hot weather.
