A South African scuba diver set a new world record after living underwater in a steel tank for 10 days and surviving by eating through a tube. Tim Yarrow was (30) cheered by hundreds of onlookers shortly after 12:30pm on Saturday when he climbed out of the 3 by 2,3m tank, his home in a Johannesburg shopping mall since November 6. Yarrow spent 240 hours underwater with scuba apparatus in a controlled environment without surfacing. The initial record was just under nine days and Tim managed 10 days, Greg Wharram, team co-ordinator, said they had contacted Guinness World Records before the attempt began and now must file papers to make the record official.
