I’m not sure if I ever mentioned it before but I was a pretty good curler in high school. Well, good is a relative term. I could make an Olympic caliber shot if the moment called for it once out of ten or twenty times. That’s the difference between your beer leaguer and your Olympic star. The guy at the club can make the perfect shot one out of 20 times. The guy you’re watching on TV will do it 18 or 19 times out of 20.
Anyway, Smarter Every Day has a handy infographic and video explaining the basics of curling and the science behind curling a stone. It seems so simple when you watch it on TV. In practice, not so much.
