Answer quickly: which sport was invented over 500 years ago in Scotland and was nicknamed "the roaring game"?
We know you didn't know. Wheelchair Curling.
Curling is also known as "the roaring game" because of the sound the rock produces while traveling over the ice.
If you think curling is tricky, wheelchair curling is even more difficult.
There is no sweeping, so the throws need to be very precise.
And no, cats are not part of the game.
Curling stones weigh up to 20 kg and are made of a rare granite that can be found only in 2 places on Earth: the Scottish island of Alisa Craig, and a quarry in Wales.
For this reason, quarries might run out of materials to make new stones in the future.
Well, maybe someone should start testing new materials ASAP!
Each team has 4 players and must include female and male athletes.
