you have a force field that the first vane you can tell it
radiometer
The shiny side of the vanes reflects the heat from the light, while the black side absorbs it. As it absorbs the light and heat, it also heats the air molecules near it. This cause the air molecules to exert a tiny bit of pressure on the flags, enough to make them spin.

A radiometer has vanes that are black on one side and white or silver on the other. There are two types of these devices, one containing rarefied (low-density) gas and one "containing" a total (or nearly total) vacuum. Both operate under different principles. In the device containing rarefied gas, light is absorbed by the black sides, which get a little warmer than the lighter sides. The temperature differential causes the gas molecules around the paddles to agitate and provide thrust to the paddles. If there is too little gas in the bulb, the vanes won't rotate because there aren't enough gas molecules to produce thrust. If there is too much gas, the vanes won't rotate because there is too much resistance (from the gas itself) for the thrust to overcome. In the other device containing a vacuum, the difference in radiation pressure between the two sides causes the vanes to spin.
The color of your vane is maroon due to the way the light hits your vane.
There are a lot of vanes in a human body. Everywhere you look on your body there probably will be vanes
there are three major types vanes are used for a centrifugal pumps those are 1.forward curved vanes 2.backward curved vanes 3.flat vanes
Weather vanes, or wind vanes measure the direction of the wind. Airports generally have high tech instruments to measure the weather as opposed to regular weather vanes.
There is no standard collective noun for weather vanes, most likely because weather vanes are seldom found in groups.However, a place that sells weather vanes might have a display of weather vanes or someone who loves all types of weather vanes might have a collection of weather vanes.
The weather vanes spun crazily. The bomb had vanes to make sure it landed nose first.
A windmill is an example of a structure with revolving vanes.
