COLUMBIA, S.C. (WIS) – Curling originated in Scotland during the 16th century, where the game was played on frozen marshes using stones from nearby. The first official curling tournament took place in 1924. At that time, the International Olympic Committee considered curling a demonstration sport. In 1998, curling became an official medal sport.
Curling stones weigh a little more than 40 pounds and move at speeds as fast as 10 to 15 MPH while in play. When releasing these stones into play, hand position and rotation speed make all the difference in its trajectory.
As curlers glide down the ice towards their stone, you’ll notice they begin a unique sweeping technique. This sweeping motion reduces friction between the stone and ice. Friction is a force that resists the sliding or rolling of one solid object over another. When curlers begin to sweep the ice, they’re creating a very thin layer of liquid that allows the stone to be steered.
The brooms used by curlers when competing aren’t something you’d find in your pantry. These are made of carbon fiber or fiberglass, with special bristles used to reduce friction on the ice. That’s how these curling stones can be guided into a particular place. Curling is a collision of sport and science that’s strategically complex, but one of the most fun events to watch during the Winter Olympics.
