A wind spinner is a decorative outdoor ornament that spins and twirls in the wind. It typically consists of a metal or plastic frame with several arms or blades that catch the wind and rotate, creating a mesmerizing visual effect. Wind spinners come in a variety of designs, sizes, and colors, and are often used in gardens, yards, or on patios to add movement and interest to outdoor spaces. They are also sometimes called wind catchers or wind sculptures.
