They left the Britain's Got Talent judges shocked with their impressive magic trick and that talented display has seen a father and son through to the semi-finals of the show.
In the recorded special that aired on Sunday ahead of next week's live shows James and Dylan Piper found out that they will take the next step in the talent show after getting a full house of judge's votes.
The Aberdare pair also had a standing ovation from the crowd and Simon Cowell, who appeared on the show which was recorded before his awful biking accident last month in which he broke multiple bones in his back.
James and Dylan are the only Welsh act in the next stage of the ITV competition which had to halt production due to the coronavirus outbreak.
They impressed Simon with a neat card trick that involved his son Eric and made it through the audition process. Giving his feedback at the time Cowell said: "That was really, really special. I love the fact it was a family affair and everything linked to him and I. I liked the presentation. It was a really great audition, all of you."
In an unprecedented move Simon declared that they had five 'yeses' because of Eric as well.
James told WalesOnline: "This really is a dream come true, we are so happy to make it through to the semi-finals."
And 13-year-old Dylan added: "It has been an amazing experience to share with my dad and I can’t wait to do it all over again."
The live shows will be socially distanced this year and with a virtual audience and they start on ITV on September 5 with former BGT winner Ashley Banjo, of dance group Diversity, filling in for music mogul Cowell.
