A teenager from Brighton is due to star in the annual Christmas Lectures, presented by the Royal Institution and televised as part of the BBC's Christmas content.
Harrison Wood, 10, who attends Shoreham Academy, Brighton, attended the filming of the historic science and engineering lectures in London and supported lecturer, Professor Danielle George, with an exciting demonstration for the show.
In this year's lectures, titled Sparks Will Fly, How to Hack Your Home, are presented by Professor Danielle George, an electrical engineer from The University of Manchester.
Professor George will take three great British inventions – a light bulb, a telephone and a motor – and demonstrate how viewers can adapt, transform and hack these every day technologies to do extraordinary things.
This is tinkering for the twenty-first century.
The 2014 Christmas Lectures will be broadcast as part of the BBC's Christmas schedule on BBC Four at 8pm on the 28, 29 and 30 December.
Danielle will announce the new rules of invention and show you how to use modern tools, technologies and things from your home to have fun and make a difference to the world around you.
Harrison came on stage to help the Christmas Lecturer play one of the biggest computer games in London. The lecture Harrison appeared in will air on 28th December.
He commented: "This is incredibly exciting and a very unexpected turn of events! So lucky to get picked.
I'm a huge computer games fan but I've never played one like this before, definitely not one this big!"
Danielle George, the Christmas Lecturer, added: "Today's generation of young people are in a truly unique position.
"The technology we use and depend on every day is expanding and developing at a phenomenal rate, our society has never been more equipped to be creative and innovative.
"If we all take control of the technology and systems around us, and think creatively, then solving some of the world"s greatest challenges is only a small step away. I believe everyone has the potential to be an inventor!"
Filmed in front of a live audience in the iconic theatre at the Royal Institution of Great Britain, the original science and engineering events for children were started by Michael Faraday in 1825 and have long been seen as a favourite British Christmas tradition.
