This is also a great science experiment.Using a ruler, you can cut a triangle that can be a pointer for the wind vane. If it isn't precisely balanced, the weather vane will topple and shift or even stop moving.
A wind vane can provide a variety of uses. Moreover, the weight balance is the core principle and needs to be extremely precise for a reading.
The wind direction is obtained from the position of a wind vane (a vertical square, triangle, or otherwise shaped wind-catcher attached to a horizontal shaft, Figure 1A and B).
