Guy Drops Basketball Off Dam, The Result Is Mind-Blowing.

Putting a spin on a ball before launching it into the air causes it to move differently — not exactly breaking news for anyone who’s played basketball, soccer, golf, or tennis. But do you know exactly why this happens?

As it turns out, we’ve known the cause behind this phenomenon since at least 1852, when German scientist Heinrich Gustav Magnus explained the mechanics of what is now called the Magnus Effect. But just because scientists have known about it for decades, doesn’t mean that the rest of us understand what’s going on.

Enter, the mind-bending video below!

A few friends decided to visit a 415-foot-high dam in Tasmania. They dropped a ball off the top to see where it would land. Though it strayed a little bit because of the wind, it landed in essentially the same spot where it was dropped.

In the next experiment, the guys dropped the ball with a little spin. This caused it to veer drastically off-course… landing in a nearby lake!

But why?

The Magnus Effect occurs when a spinning ball, cylinder, or similarly shaped object curves away from its intended path because of changes in air flow. In the case of the basketball, its intended path was straight down, but it veered off because of the spin.

“As the basketball picks up speed, air on the front side of the ball is going in the same direction as its spin, and therefore it gets dragged along with the ball and deflected back,” the narrator explains.

The video has been viewed by more than 35 million people since it was posted just two years ago and everyone is loving how easy to understand the concept is and how cool the demonstration was.
