American magician David Blaine is to be suspended in a glass box over the River Thames in London [9]for six weeks without food. The 30-year-old New Yorker is famed for spectacular feats like being frozen in ice. He is to be placed in solitary confinement on September 5 in what he calls "the most extreme exercise in isolation and physical deprivation ever attempted." Against the background of London’s Tower Bridge, [9]he will spend six weeks suspended by a crane in a clear box "with no food, no communication and no distractions of any kind." He will have one tube to give him water and another for urinating. [10] "We are all capable of infinitely more than we believe." said Blaine. His endurance test will be shown live on British television.
    Blaine rose to fame with his "street magic" displays in New York. This will be the first time he attempts a major feat outside the United States. [11]Over the last decade Blaine has become famous with a combination of breathtaking magic and sharp publicity feats, using television specials, celebrity friends and unusual tests of endurance to earn millions of dollars and thousands of fans. In May 2002, for example, Blaine climbed an 80-foot pillar, about 25 meters, in New York City and stood on a platform the size of a large pizza box for 35 hours before jumping into a pile of boxes. Other recent feats have included standing for 62 hours in a giant cube of ice in 2000 and a week-long stay in a buried coffin in 1999. [12]All were shown live on television.
