They're also surprisingly counterintuitive. For instance: who here thinks that the sweepers' job is to increase or decrease the friction of the ice in front of the stone to make it curl? I definitely did. Turns out that's totally wrong. And it's still not even the weirdest thing about the physics of this sport.
If you are mystified by the sliding and sweeping sport that is curling, Sir David Attenborough is here to help. BBC Radio 1 convinced the naturalist to narrate a few moments with Great Britain's Olympic curling team as if it were a nature documentary.
