Flettner Rotor Sail Cart // Homemade Science with Bruce Yeany

The Flettner rotor is a large spinning cylinder that was originally developed to harness wind energy for moving large transport ships. It was introduced during the 1920’s and uses the Magnus Effect to capture the wind instead of a more traditional sail found on older boats. In this video a small cart has a large spinning rotor attached is used to demonstrate how the Magnus Effect and the Coandă effect are the result of Bernoulli’s principle.
