Bumpy science behind golf balls
WHY DO GOLF BALLS HAVE DIMPLES?
DIFFERENT DIMPLES: The dimpled surface of the golf ball has gone through many iterations. In 1848, the gutta-percha ball sported inverted dimples and was covered in a pattern of protruding squares to minimise drag. In 1899, American inventors Coburn Haskell and Bertram Work patented a gutta-percha golf ball with a rubber core. Their design lasted until the early 1900s, when more robust plastics were being developed. Manufacturers found that balls with concave dimples would fly better than a gutta-percha ball. Although it might be hard to differentiate between modern-day golf balls, the number of dimples and the shape of dimples can differ.
Golf ball dimples are created by filling moulds with plastic around rubber cores
Do you know:
● The average golf ball dimple depth is 0.25 millimetres.
● A golf ball with dimples can travel almost twice as far as a smooth ball.
