Britain's Got Talent viewers came up with a number of fan theories as a magician blew their minds with his tricks.
Magical Bones, aged 37 from London, performed a magic routine incorporating escape artistry with close up magic, telling the story of the slave Henry Brown.
His first performance saw him correctly pick Simon Cowell's card out of a deck whilst doing a backflip.
But if that wasn't impressive enough, Magical Bones moved onto his next illusion.
He placed a woman into a box full of swords before wrapping a curtain around the box.
Magical Bones, wearing a red hoodie at the time, walked behind the curtain, but out of the other side came the woman who was in the box.
Pulling back the curtain, it was revealed 'Magical Bones' was now in the box.
However, when his assistants opened the box, it wasn't Magical Bones at all - it was another woman.
She then pointed behind Simon and when he turned round Magical Bones was there.
Everyone was stunned by the magician's act, questioning how it even happened.
And of course, some viewers came up with their own fan theories.
Joy said: "I ain’t no magician but the lady was obviously behind the curtain the whole time and then he went behind the curtain ??"
Another said: "Everyone was hiding behind the curtain?"
Mark tweeted: "There was two women there at first, he was never in the box, two women switched places and he went from behind the box to behind the curtain."
Ben attempted to give it a go: "Even pausing and looking at the magic act it’s hard to see how they did it. Tho looks like double curtain at back but how would he have got to the audience? Someone explain it lol."
Magical Bones' talent managed to score him four 'yes' votes, seeing him through to the next round.
