A stirrer is a tool used to mix substances, typically liquids, to achieve a uniform consistency. It can be made from various materials, including wood, metal, or plastic, and comes in different shapes and sizes. Commonly found in kitchens, laboratories, and industrial settings, stirrers help combine ingredients or solutions effectively. In cooking, a stirrer is often used to blend ingredients in pots or bowls, ensuring even distribution of flavors. In scientific applications, such as chemistry, a stirrer may be used to mix solutions in beakers or flasks, often accompanied by a magnetic stirrer for automated mixing.
