The Coanda Effect

More at http://www.laesieworks.com/ifo/how/Co... • An experiment showing the Coanda Effect: A fan blows a jet of air in all horizontal directions. Instead of shooting away straight, the air follows the curved surface, even when starting from a step pretty far above the surface. The air pressure between the surface and the airflow is lower than the surrounding air. The thrust from this devise is up to 450 grams. Don't believe the fast air has less pressure myth, because speed is relative. The air in between gets party removed by the jet of air, and the surrounding air pressure pushes the jet towards the surface. That is what is happening. And yes you could build a flying saucer with the coanda effect. Cool but probably not very efficient practical.
