If you are looking to try out a new scary hobby, then take a look at this slack lining. Thrill seeking and some may say fool hardy. Dean Potter from the US walked on a rope known as a slack line, which is only two centimetres thick, across a canyon in central China, a whopping 1,800 metres above sea level.
Seen here balancing precariously in his bare feet, the slack line isn't as taut as a conventional tightrope, so lots of bouncing and stretching as you can see. But he covered 40 metres in just over two minutes without a tumble and hardly looked down at all.
