Magnus Pendel

A red ball is pivoted to the end of a pendulum. The ball is mechancal connected with the pendulum. So the ball sometimes rotates left - sometimes right. The magnus-effect gives the pendulum always an impulse in the correct direction to swing up. The magnus-effect was discovered in 1852 by the German physicist and chemist Heinrich Gustav Magnus. In football, golf and tennis it is helpful for the sportsmen, even if the spinning ball describes a bow in horizontal level. It has been tried once even to drive large sailing boats with enormous rotating cylinders (flettner sail).
