What makes dimples on golf balls so effective?
Quick fact
Dimples create a thin turbulent layer of air around the ball that reduces aerodynamic drag by up to 50% and also generates lift through backspin.
Why this is interesting
A smooth golf ball would travel only 130 yards, but the same swing with a dimpled ball sends it soaring past 250 yards—dimples are the ultimate aerodynamic cheat.
