Tapescript
Presenter:... and now we're going to take a look at extreme sports. More and more people are taking them up, but what exactly are they? How dangerous are they? What makes people risk their lives to do them? Michelle is going to tell us all about them.
Michelle: Speed, excitement, danger. You can find all these in the various extreme sports that have become popular in the last ten years or so. Take bungee jumping. You jump off a high bridge, like this one I'm standing on now, and you fall and fall, and then, just before you hit the ground or water, an elastic rope pulls you back. No way! There's no way I'd go through with that, I'm telling you! And other extreme sports appear just as crazy. Look at this video. In sky surfing you jump out of an airplane and use a board to 'surf the air, doing gymnastics in mid-air! Amazing, isn't it? And extreme sports on land can be just as dangerous. Winter sports have always had an element of danger. I'm into skiing myself and I've had a couple of nasty falls. But new sports like snowboarding, extreme skiing are much more dangerous. Probably the most dangerous of the new winter sports is snow rafting. It's difficult to get across just how dangerous it is but imagine - you sit in a rubber boat and 'sail' down a mountain at great speed - and you can't control the boat! Crazy, isn't it? Of course, water sports have always been fun. In white water rafting you sit in a small inflatable raft and go down a river at great speed. Fast flowing mountain rivers are the best. Then there are sports like ice-cannoning and ice diving, for those people who are absolutely crazy. Ice diving is not easy to set up because you need good diving equipment and a frozen lake. First you break the ice and then you get into the fatter. Sounds fun, doesn't it? And, if that’s not enough, you then try to walk upside down on the ice! Mm, I feel cold just watching it...
