Curling is perhaps one of the strangest sports to watch, involving big rocks, a target painted on ice and people sweeping furiously with brooms.
It's played in teams of four people, and teams take it in turns to slide eight stones across the ice towards a target, trying to get as close to the centre - called the tee - as possible.
The team with the nearest stone to the tee scores a point, and for every other stone nearer the tee than their opponents', they score another point.
What makes curling so curious to watch though are the two team members who use brushes to try to control the slide of the stone.
Each team member has two stones to use, and the team with the most points at the end of 10 team turns - or ends - wins.
