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.
