If you love science, then you will love this article on Magnus Effect. It's amazing how can a basket ball fly in the air with the help of a backspin ?
All thanks to Magnus Effect.
In the video, it shown what happens when you drop a basket ball from a 126 feet heigh dam in Australia. It falls on the ground straight (more or less) but when a you add a spinning on the basket ball, it fall after taking a fly horizontally in another direction.

Why ??
Because, Magnus Effect... An effect when applied on a rotatory object whether it's circle or cylindrical it flies, in the air.
As video says, "As the basketball picks up speed, air on the front side of the ball is going the same direction as its spin, and therefore it gets dragged along with the ball and deflected back. Air on the other side is moving opposite to the ball’s spin, so the flow separates from the ball instead of getting deflected. The result is that the ball pushes the air one way so the air applies and equal force on the ball the other way."
Magnus effect is widely used in games like soccer, football and etc. But what is real use ??
In the video, you'll also see a Rotor Ship, Flettner Rotor. Flettner Rotor uses the same concept of Magnus Effect. It has two cylinders, which spins and pushes the ship forward.
It's also used in airplanes also. So we're seeing at the future, with some promising Magnus Effect Applications.
