Every four years Curling, always a tough sport to explain to those who don’t know the rules, gets a bit more exposure through the Winter Olympics. But you don’t need ice, granite stones or brooms. It turns out you can play it on water, with a tea kettle, floor squeegee and a lot of enthusiasm.

Curling has been an Olympic sport since 1988, but it was also part of the program in 1924 before it was shelved for over half a century. Canada won the gold medal in 2006 and 2010 in the men’s competition, and are in the semifinals this time as well, with Great Britain, Sweden and China rounding up the final four for the men. In the women’s side of the competition, Switzerland replaces China in the final four. Sweden are the gold medalists in 2006 and 2010 for the women.

So who do they do this in Brazil, especially when everything is soaked from rain? All you need is something you can slide through the water, and a mop to clear its path on the not so even surface. It’s not looking like something that’s going to catch on as a sport, but if Curling is grabbing headlines once every few years, why not this?
