Cloud’s fate now lies in the hands of the viewing millions, with a phone vote deciding who makes the semis.

However, judges felt that he hadn’t explained the set-up to his trick very well. Cowell said: ’I think your showmanship and your explanation has got to be better.’

And Mandel added: 'I think it was long and drawn out and confusing — everything was confusing me.’

But Mel B praised Cloud as ‘incredible’.

Cloud – dubbed the ‘real life Sherlock Holmes’ – also successfully figured out what embarrassing moment one random audience member was thinking of.

But for the main trick he guessed the name and occupation of another punter – chosen by Mel – then the reason she would like to kill Cowell.

The woman then selected one of five knives. which was handed to the former Spice Girl as she stood behind Cowell. But when told to plunge it into the impresario’s chest, she found that it had a rubber blade.

The current season of America’s Got Talent has been topping 13million viewers in the ratings. And already Cloud’s appearance on the show has attracted 500,000 views on YouTube.
