Why does a golf ball have dimples?
It's a simple question, but according to Business Insider, they play a big part in how far that ball can fly.
A dimpled golf ball can travel nearly twice as far as one without dimples.
The trick is how the ball interacts with the air around it.
The dimples create tiny air currents that change direction around the ball.
A golf ball has between 300 to 500 dimples.
