A man is attempting to walk across the Irish Sea - in a human HAMSTER WHEEL. Chris Todd, 35, from Bromham, Wiltshire, will zig-zag 66 miles across open water for two days non-stop. He will power his metal wheel - which he calls a Tredalo - by walking on wire mesh, with two floats either side to act as stabilisers. Todd still hopes to raise £20,000 for charity, and plans on making another attempt at the crossing later this month. He will consume a whopping 30 litres of water and munch the equivalent of 60 Mars bars to keep energy levels up. Donations can be made through his website.
