This new sport isn't really taken seriously by most people,but it's becoming quite popular! All you need to do it is an iron and a board - an ironing board! Of course the irons are special ones which run on batteries. You then have to take some clothes and iron them in an 'extreme' place like the top of a mountain, on a raft or even underwater! So far some of the extreme places the activity has been done include Mont Everest and the South Pole!
