Fans were giving the magician a hard time on social media.
Dynamo admitted something could go wrong during his live televised show this evening.
Sadly for the incredibly talented magician, there was a hiccup as he took to the stage for Dynamo Live At The O2 in front of the likes of Danny Dyer, Pixie Lott, Professor Green and Kimberley Walsh.
After he invited two guests to get involved with one of his tricks, he wowed the audience by making a young male’s phone disappear before reappearing in an empty water bottle.
In a bid to prove that it was the gentleman’s phone, he asked his other volunteer to ring his number.
At that moment disaster struck.
With thousands of people sitting in London’s O2 Arena all at once, mobile phone signal wasn’t exactly the best.
So when Dynamo’s female volunteer attempted to call the phone, it didn’t work. Cringe!
