Living in a box: Week one over

American illusionist David Blaine has marked his first week suspended in a glass cage without any pomp or ceremony – just a dirty nappy.

Blaine, who began the stunt on Friday last week, hid under a blanket before dropping the bombshell from his home in Tower Bridge to people on the ground.

A spokesman said: “He managed it at around 2am on Day Six. It all went in a bag which he threw out of the box to people on the ground.”

But it failed to impress singer Gloria Estefan who described it as “revolting”.

The Latino star and her nine-year-old daughter Emily were among the crowds watching Blaine.

“I was watching him up there and all I could think was – how is he going to the toilet?,” she said.

Told that Blaine had taken a supply of nappies in with him, the 46-year-old who is in London to promote her new album, Unwrapped, said: “That is so revolting. It must smell disgusting in there.”

As Blaine headed into the second week of his 44-day challenge the strain of the task facing him was, according to observers, beginning to show.

“For the first few days, David kept his spirits up and seemed to be doing well,” one said.

“But now he has become lethargic and his movements are much slower. He is obviously finding it tough going now.”

Consultant psychologist Dr John Potter, who has been monitoring Blaine, said: “The settling down period, otherwise known as the honeymoon period, lasts for around seven days.

“Now things are getting harder. The most interesting stage will begin after 12-14 days when David can expect to suffer hallucinations.”

The on-site medic, Dr Adam Carey, said Blaine would have lost up to 5% of his body weight over the past week.

He has been drinking four litres of water a day and producing three litres of urine, which is passed through a tube to the ground where it will be analysed for signs of kidney or liver damage.

The New Yorker has been sleeping for a total of about eight hours a day, although passers-by have been doing their best to keep him awake.

Since entering the box fans have hurled eggs, golf balls and insults in a bid to gain some kind of reaction.

Dr Carey said: “During the first couple of days he will have used up the carbohydrate stores in his liver and his muscles.

“By the end of the second day the body also starts to break down muscle and to release amino-acids which are then converted into glucose to feed the brain. He will be burning off body fat to produce the fuel he needs.”
