The Answer Is Blowin’ In The Wind
- The rod is the vertical piece that attaches to your roof; it functions as the pivot point for the directionals and the arrow.
- The directionals, indicating North, South, East and West, sit stationary on the rod; when the wind starts to blow, the directionals don’t budge.
- The arrow is positioned above the directionals. One side of the arrow has a tail fin, the other has a point. When the wind blows, it catches the tail fin and pushes it straight back, swinging the opposite side, the arrow point, in the direction the wind is blowing from.
