Question
[Magnus Effect?
Answer

mean, it really flies. It's thanks to the Magnus effect, which occurs when the air on the front side of a spinning object is going the same direction as its spin, which means it gets dragged along with the object and deflected back.

Meanwhile, the air on the other side of the ball is moving in the opposite direction, so the air flow separates.

Watch Veritasium explain it better than we ever could:
