The 'daunting' task of being the youngest magician to perform at Edinburgh Fringe Festival

"It's such a daunting task," admits Callum McClure, ahead of his Edinburgh Fringe debut show.

Aged 19, he's the youngest magician to perform at this year's festival, the largest arts show in the world.

"It's not something that young people do these days," he explains to Newsbeat.

Despite being a free show, he has only 250 words in the show's online description to "sell it" to a potential audience.

"I'd describe my show as a modern and classic mix between all sorts of magic, and robotics as well," he says.

"It's very difficult because there's so much you want to say."

Ahead of his first show, Callum posted on Twitter: "Opening night for Callum McClure: Deception! After loads of hard work, it's finally here."

Callum has a robotic assistant that helps perform tricks, as well as reacting to the show and audience.

"It's an added personality in the show," he laughs.

"I started when I was about seven years old. I was really interested in the kids' sets you get when you're younger.

"It really took off [for me] when I stopped reading the instructions. It sounds silly but the moment I started doing something completely different it started being, 'Wait. What? Show me that again.'"

Watch Callum perform a magic trick on the Royal Mile for Newsbeat.

When he was 12 he began performing for money to raise funds so he could see magic shows in Las Vegas, and, over the past four years he's developed his show Deception.

It's won him national and international awards, and he was runner-up at the Young Magician of the Year Awards in 2015.

He's also part of the Magic Circle, joining acts like Dynamo on their roster, but that doesn't calm his nerves.

"Hopefully it all goes swimmingly," he nervously laughs backstage at the Voodoo Rooms.

"I'm a little nervous and worried about how the robot will perform, and the audience reaction."

He tweeted: Such a great show! Lovely positive reviews. All the hard work has paid off.

So how deceptive was his deception?

There were audible gasps from the audience on multiple occasions, applause after most tricks and some genuine shock.

"You couldn't really see him pulling any fast ones," said one audience member on the front row.

"I'd definitely recommend him to a friend."

But what's Callum's own view?

"I'm proud of myself," he says. "And I'm looking forward to the next 10 shows."
