Britain's Got Talent viewers rumble 'magic marine' - but he's a hit with the ladies

Britain's Got Talent viewers took to Twitter after Saturday's episode to figure out how "magic marine" James Stott performed his stunts.

James correctly guessed which boxes would explode on stage and was so sure he knew which one would not explode, he took the wire out of it and placed it in his mouth.

He also shocked the judges when he guessed which bag on the table had a dagger in it, slamming his hand down on the other bags which were thankfully empty.

But eagle-eyed viewers guessed how the stunts worked and predicted James was never in any danger.

"Am I the only one who thought the Magic Marine was s**t? Obviously knew which box was linked to which plunger... #BGT #BritainsGotTalent " wrote one.

"I thought that the red device he was holding was part of a circuit, when he took it out the explosion didn’t happen. When he put it back it did," another user replied.

"And he swapped it, then tried to distract that he knew he had the wrong one by putting it in his mouth. Absolute balls. You've seen one of those tricks, you've seen them all."

Another viewer predicted: "I think... More like the wires aren't actually attached to any explosives. Explosives are detonated remotely. Wires are gimmicks."

"Wasn't impressed by the marine magician. The first trick was probably someone in the audience telling him which bag to pick. And the second trick just had flash bangs in the boxes, loud and smokey but pretty much harmless. He was never in any danger," added another.

Another penned: " #bgt (little behind but the Marine guy with the knife and boxes) so all the cards said 5 since we didn't see the others. And he must know which plunger linked to each box since he changed boxes at the end. I like that kinda stuff but very simple how it's done . Let down :/ ".

But other viewers were huge fans of James, particularly some lusty women who appreciated the navy hunk.

"Anyone else feeling a little hot after watching the magic marine," asked one.

"Wow ... The Magic Marine was incredible," added another, alongside a love heart eyes emoji.

"The magic marine.. oooffff" added a third.

"Hot ex marine," gushed a fourth.
