John Doernbaum walked up to the judges’ table on Britain’s Got Talent with a £50 note in his hand and a simple question: “May I come and join you at your table?” What followed was a 63-minute run of thirteen card tricks that turned the panel from polite observers into people who swore, on camera, that they were witnessing real magic. The video captures the full hour, uncut, and the pacing is what makes it work. Each trick builds on the last, and by the time the final card is revealed, the judges have stopped performing skepticism.
The opening trick was pure misdirection. Doernbaum rolled up his sleeves, held the note up for the cameras, and changed it into a “Bank of Britain’s Got Talent” £50 note featuring Simon Cowell as head of state and the other judges as “beautiful princesses.” He handed out copies to the audience. “Don’t spend it all at once,” he told them. The joke landed, but it was a warm-up. The real trick was still coming, and it involved a card that four people had chosen in front of him, one at a time, with no way for him to know the final answer.
The Card They Couldn’t Have Known
Doernbaum drew a self-portrait on a card, sketched the stage, and then asked each judge to make a single choice. David picked black. Felicia picked clubs. Amanda picked nine. Simon, given the chance to overrule everyone, chose the seven of hearts. “There is no way I could know that you would choose the nine of clubs,” Doernbaum said, holding the deck up. “There’s no way I would know if you would overrule, and if you would, what you would change to.”
He then flipped through the back of the deck, where he’d drawn a cartoon flip-book animation. A little magician took off his hat, reached inside, and pulled out a single card. The seven of hearts. The audience gasped. Simon leaned forward in his chair.
“I know this sounds crazy, but I now actually believe in magic,” Simon said. “Like some people believe in ghosts, I now believe in magic because there’s no explanation for that. None whatsoever.” David called it “one of the best magic work I’ve ever seen” and added, “It’s not a trick. It’s real magic. He has magical powers.” Alicia said it would “bug us for the rest of the day.” Heidi told Doernbaum he was “fast with your hands” and “fast with your mouth” and “charming.”
Shooting Cards Like a Machine Gun
The second trick was faster and messier. Doernbaum folded a card into a paper clip, placed it in front of Mel B, and then began riffling through the deck, calling out numbers. “Stop,” Mel said. He shot a card. “Stop.” Another. Each time, the card he pulled matched the number he’d announced. Two, three, four, five, six, seven, eight, nine, ten, jack, queen, king. He worked through the entire sequence in under a minute, riffling and shooting with a speed that made the judges lean forward in their chairs. The comedy magician’s number one trick, he called it, and he delivered it without breaking rhythm.
Then he asked Simon to think of a card. “Three of clubs,” Simon said. Doernbaum shuffled the clubs into order, flipped the deck, and the three of clubs sat in the paper clip. “I could see it never moved,” Simon said afterward. “For someone who doesn’t do this professionally, it was so slick, so fast. Your dialogue is great. It’s not a trick because it’s magic. It was amazing.”
The Cake
The third trick was the one that made Howie Mandel laugh the hardest. Each judge picked a card, memorized it, and put it back in the deck. Doernbaum found Simon’s three of diamonds, Sofia’s ace of spades (after a brief “ace of the shamrock” mix-up that had the panel cracking up), and Heidi’s queen of hearts. Then came Howie, who’d signed his card with a star and the word “Howie.” The deck was now blank. Every card had vanished.
“What does every celebration need?” Doernbaum asked. “A cake.” A cake appeared on the table. Inside it, nestled in the frosting, was Howie’s one-of-a-kind signed card. “Thank you, America, for making me feel like a winner already,” Howie said, holding it up. “I love you.”
Gambling Cheats and Burning Decks
The video doesn’t stop with Doernbaum. A second performer, working with a more technical, almost surgical style, demonstrated how gamblers cheat. He showed David a card switch: the three of spades on top becomes the two of hearts the instant it hits the table. He performed a false count, making one card look like ten, then dealt to a number David chose and produced the two of hearts on the sixth card. “This is too hot,” David said, shaking his head. The performer then found four specific cards in the deck by counting the gaps between them, a technique he described as “the quickest way to find these four cards.”
Other tricks in the hour push the format further. One magician burned an invisible deck of cards, asking the audience to choose whether to “burn all the men or all the women.” Another sealed a prediction with a kiss. One performer tossed all 52 cards straight at the hosts, catching them mid-air. A ring trick ended with the line “It was just a memory. The ring was never there,” leaving the panel genuinely unsettled. An empty box was no longer empty. A brand-new deck was revealed to be the end of a sequence that had started at the beginning. One performer told Howie, “I just wanted to touch you,” and then made him reach into his left back pocket for a card that had never been there.
What You Were Born to Do
Thirteen tricks in 63 minutes is a lot of magic to pack into one sitting, and the video’s strength is the variety. You get the slow, narrative card work of Doernbaum, the rapid-fire technical displays, the physical comedy of tossing a full deck at a room full of celebrities, and the quiet, almost eerie moments where a ring vanishes and nobody can explain why. The judges’ reactions track the shift: polite applause early on, then Simon’s “I could see it never moved,” then the full “this is what you were born to do” verdict that lands near the end. One judge told a performer, “I thought it’s a magic trick. Now you’re doing chores,” which is about the highest compliment a magician can get from a panel that has seen a thousand acts.
The video is a masterclass in how card magic works on television. The tricks are not the most complex in the art, but the pacing, the dialogue, and the way each performer reads the room make them land harder than they should. Watch it once for the tricks. Watch it again for the way Simon Cowell slowly stops pretending he’s not impressed.
