The other end of the pencil that we usually use to write can go into a block of clay, so it is kept stable. This should be stable for a well-made wind vane. You can now insert a pin right in the center of the straw, then attach it to the eraser on the top of the pencil. Your structure should look like an arrow now. Once the slits are made, you can open the straw up at the top and stick the triangle on one side and the square on the other side. These slits should be approximately 1 cm in length.

It is best to keep the lengths identical but not necessary. Once you have both the pointers ready, you can cut evenly measured slits on both sides of the drinking straw. Now, the square and the triangle can be the two sides of your wind vane. Next, you can draw a square that is about 7 cm on each side. This should be approximately 4 cm at the base, and 5 cm tall. Using a ruler, you can cut a triangle that can be a pointer for the wind vane. There are lots of different ways in which you can make a wind vane. Observing and following a wind vane's model accurately makes it easier for us to understand how it works. This prevents any other tall structure of building from manipulating the wind's direction and affecting the wind vane's reading. It should ideally be installed at the highest point of the building. Another factor that affects the wind vane's working is the height at which it is installed. This allows us to read the wind vane accurately, even from a distance. It is crucial that the directions - north, south, east and west, are marked on the wind vane. To read the wind vane accurately, it is essential that it is marked correctly. The wind vane rotates on the axis, and it also allows it to spin freely. Although the shape can be unequal, the weight has to be equal on both sides of the structure's vertical axis. This helps so that the lighter and smaller area can face the direction that the wind is coming from. Another critical factor to keep in mind is that the construction works best when the design is not symmetrical.

This means that there is free movement of wind, especially around the vertical axis of the structure.

It has a traditional arrow shape with a ship on top.Ī critical principle in the working of wind vanes is that the design and construction should allow unrestricted movement of the wind. It measures 48 feet (14.6 meters ) tall with an arrow measuring 26 feet (7.9 meters) long. The world's most giant functional wind vane can be found in Montague, Michigan. Nowadays, there are many kinds of wind vane. The motif on the wind vane was of Triton (the Greek god of the sea) with a wand, which indicated the wind direction. The first Wind Vane was recorded in 48 BC by Greek astronomer Andronicus. The direction which the motif faces is generally the direction from which the wind is blowing. Some common motifs which are used for wind vanes are ships, arrows, horses, and cockerels. A wind vane is highly functional but also used for decorative purposes nowadays. The word "vane" actually comes from "fana," which means flag. It is a common sight on buildings, especially on the highest point of the building. A wind vane is an instrument that helps to show the direction of the wind.
