The Magnus effect in action. Named after Heinrich Gustav Magnus, this phenomenon is observable in a spinning object. As a ball moves through the air, its spin is moving against the flow of air on one side, towards the air on the other. So, the object drags air faster around one side, creating a difference in pressure that moves THE OBJECT in the direction of the lower-pressure side.

Magnus-effect model aircraft use spinning cylinders instead of traditional wings, and watching them fly is almost unreal. As the cylinders rotate, they create lift in a completely different way, letting the aircraft glide, curve, and climb with smooth, almost floating motion. Hobbyists have been testing new designs that look simple but perform with surprising stability, proving that alternative aerodynamics can be both fun and incredibly effective at small scale. | Fadhel Mahdi
