One way to make a simple anemometer using paper cups is to follow these steps: Cut out four equally sized circles from a cardboard or foam board. These will be the blades of the anemometer. Punch a hole in the center of each blade, and then attach them to a central spindle using brads or small screws. Next, attach a paper cup to the bottom of the spindle so that it is upside down. Now, attach a second paper cup to the top of the spindle so that it is right side up. Place the anemometer in an open area where it will be exposed to the wind. As the wind blows, the blades of the anemometer will spin, causing the top cup to spin as well. To measure the wind speed, use a stopwatch to time how long it takes for the top cup to make a complete revolution. The wind speed can be calculated using the following formula: Wind speed (mph) = (60 / time in seconds) * (diameter of top cup / diameter of blade) This is a very basic anemometer and is not as accurate as more sophisticated devices, but it can give you a rough idea of wind speed. ==================== Materials Used : Color Papers : https://amzn.to/3ir1uDo Threads :https://amzn.to/354qyrZ Glue Gun : https://amzn.to/356h7bt Glue Sticks : https://amzn.to/3pCAGlc Scissor : https://amzn.to/2SpBgGz Cutter : https://amzn.to/3vgTQyk Fevicol :https://amzn.to/3zfNYse Paint : https://amzn.to/3pIfBG6 Paint Brushes : https://amzn.to/2SonJPF Robo DC Motor : https://amzn.to/3g7kN31 DC Motor : https://amzn.to/3zhrcQD DC Water Pump - https://amzn.to/3izSE6e Switch : https://amzn.to/3gmvNbM ================================= Tripod :https://amzn.to/3xd29fS Camera : https://amzn.to/3zgGFR3 Laptop : https://amzn.to/3x5i1AS ================================ Amazon - https://www.amazon.in/shop/howtofunda Website - http://howtofunda.com facebook -   / howtofunda   twitter -   / howtofunda   instagram -   / howtofunda
