Here's how it works:

* Shape: Windsocks are typically cone-shaped or cylindrical, with a long, open end that faces into the wind.

* Material: They're made from lightweight fabric, often nylon or polyester.

* Movement: When wind blows into the open end, the sock fills with air and aligns itself in the direction the wind is coming from.

Windsocks are commonly used at airports to indicate wind direction to pilots, but you can also find them at boat docks, sporting events, or even just as decorative elements in gardens.
