a wind vane
If it's the kind of wind vane I'm thinking of, it has a pointy end and the tail end. The tail end has fins or other things sticking out of it that catch the air and create drag. So that end will go 'downwind" or the way the wind is GOING. The other end of this stiff metal object will then point INTO the wind, meaning it points the direction the wind is coming from. This narrow pointy end does not give the wind much resistance compared to the tail. So that's why the tail end goes downwind and the stick or bar pivots on an axis and the pointy end points into the wind.
