what does a weather vane do?

Shows the direction of the wind.

Answer 2

A weather vane is a swiveling pointer designed to be mounted at a high point on a building so that it can swivel freely to point into the wind, thus showing the direction of the wind.

It is more correctly called a "wind vane," but the term "weather vane" was used in the 18th and 19th centuries when the wind direction was considered a more certain predictor of the weather than it is now.

Many weather vanes were made in various decorative designs. Try an internet search on "weather vane."
