Dynamo was left red-faced after a magic trick he was performing in front of thousands of fans during a live show went wrong.
The Bradford-born magician, whose real name is Steven Frayne invited two audience members onto the stage as part of his Dynamo Live at the O2 Arena.
One man called Tom volunteered to let the magician make his mobile phone disappear and then reappear in an empty bottle.
To prove that the phone was Tom’s he asked the second volunteer to call the phone but it failed to ring.
