A weather vane, also known as a wind vane, is a device used to show the direction of the wind. It typically consists of a rotating pointer mounted on a fixed mast, which indicates the wind's direction by aligning itself with the wind flow. The pointer often has a design (such as an arrow or a specific shape) that makes it easy to read.
