Eagle-eyed BGT fans ‘expose’ secret that shows how golden buzzer star Keiichi Iwasaki does mind-blowing tricks

BRITAIN'S Got Talent's viewers reckon they have figured out how golden buzzer magician Keiichi Iwasaki does his incredible tricks.

Theories have done the rounds since last Saturday's episode of the ITV show, where the Japanese street magician got Ant and Dec's golden buzzer.

The illusion that got everyone talking was a flying ring trick where a ring defied gravity to land on Alesha Dixon's finger.

Initially fans claimed he was using a piece of invisible string to make the jewellery spin through the air, but now some other viewers believe the secret lies in the black bag Keiichi was wearing on his waist.

"I'm thinking that the little black bag on his belt has something to do with it," one commented on social media. "Some kind of magnet in there or something."

"The device is an electromagnet to create a magnetic field," explained another. "The ring also contains a magnet with an opposite pole to achieve magnetic levitation. The spin is due to the lorentz force."

Another believed there was a magnetic 'device' in Keiichi's hand, claiming they could "see the device on his right middle finger".

Regardless of the secrets behind his tricks, Keiichi scored lots of praise from viewers who were blown away by his act.

One viewer on Youtube, where the act has already racked up more than 3 million views, said Keiichi "deserves his own spot in Las Vegas".

Others compared him to magic legends Penn and Teller.

But some fans felt frustrated by the fact that Keiichi has already appeared on four other Got Talent shows.

It turns out the magician has appeared on other editions of the global franchise in Bulgaria, Spain, Italy and Germany.

As a result, the show issued a statement defending Keiichi and reminding viewers that there are no rules against acts appearing on multiple versions of the series.

A rep said: "As with many other entertainers who are hoping for success in the industry, Keiichi, a street performer, had previously auditioned on television shows in the past.

"There are no rules that state this should prevent him from applying.  All acts audition on the same basis and normal programme rules apply."
