A Windsockis used at airports to indicate wind direction for takeoffs and landings. They help the pilots select the proper runway so that they can take off and land into the wind. Wind speed is indicated by the windsock’s angle relative to the mounting pole; in low winds, the windsock droops; in high winds it flies horizontally. Windsocks are also popular with children and can have bright and colorful designs. These windsocks are not particularly functional and are mostly for decoration.
