Dynamo has told how he hopes to use his magic to inspire children to follow their dreams.
The 31-year-old magician surprised seriously ill children at a London restaurant when he appeared as the waiter and then entertained them with magic tricks.
Dynamo - who has Crohn's disease and has spoken in the past about his difficult upbringing - is an ambassador for Rays of Sunshine Children's Charity.
He said: "Meeting these children is so humbling and overwhelming. Just to be able to put smiles on their faces, that's what it's all about really.
Dynamo, whose real name is Steven Frayne, went on: "Having Crohn's myself, having lived through that, it puts things into perspective a little bit, so I can empathise with what these kids are going through.
"And also what it's like for the parents who are looking after them, who don't necessarily know how to deal with it, because unless you've got it it's hard to understand it.
"So to be able inspire these people and show that it doesn't matter what you've got or any problems you've got in your life, you can still make something of yourself or have confidence to get out there and do something.
"Because when I was growing up I didn't have anybody to do that other than my grandpa, and without him inspiring me, I wouldn't be doing what I'm doing today. So it's great to be able to inspire these guys."
Amongst the children Dynamo surprised was eight-year-old Harry from Leeds who is living with Acute Lymphoblastic Leukaemia. Harry's parents bought him a magic set when he was first admitted to hospital and since then magic has become a big part of his life. Harry is a big fan of Dynamo and got the chance to demonstrate one of his favourite tricks to his idol.
