Height of success

In Romania two thrill seekers climbed a crumbling industrial chimney some 256m high and filmed themselves riding around the top on a unicycle. To reach the top they had to negotiate rusted walkways and ladders that were missing some sections. Once at the top the two pranksters amused themselves riding round and around the chimney, hopping over obstacles and seemed to take great delight in doing so, despite loose brickwork. Remarkably they survived to upload their footage to Youtube.
