A schoolboy will star on a children's TV show after he spent three weeks working in some of the world's poorest countries.
Mattie Barnett, from North Kesteven School, will be in all five episodes of Show Me What You're Made Of on the CBBC children's channel.
He was one of five youngsters to be selected for the programme.
The group travelled to south-east Asia and lived alongside people who make the things we use everyday.
Each installment of the BAFTA-nominated show, now in its second series, will be on the CBBC channel at 5pm from Monday, December 10 to Friday, December 14.
Mattie, of Witham St Hughes, said: "It was amazing – completely life-changing.
"The way people live and the way they work is completely different from back home. It was really intense."
Mattie said the experience had made him vow to spend more time with his parents and appreciate his home life.
"It's changed the way I treat my family," he said.
"Over there they do everything for their families. It's everything. All they do is work for food.
"It made me realise how lucky I was."
The first episode sees the group leave their comfortable Western lifestyles and fly 6,000 miles to Malaysia to work in a rubber shoe factory.
Other instalments show the team travel to Thailand and Indonesia as they clock up 15 flights during their adventure in August earlier this year.
Mattie's mum Rachel, 39, said her son had come back from the trip with a new perspective on the luxuries enjoyed in Britain.
"One of the main things that he's taken from this is not to take things for granted in life," she said.
"He's so much more grown up now – not that he wasn't quite grown up already, but he's seen so much.
"Part of the trip showed how much effort went into making each individual bit of the programme and I think that's one of the main things he took away, as well as the experience."
Tuesday's episode will show the group land in Thailand for a spell in a cosmetics factory, where they endure long shifts completing the same tasks.
Bangkok is the next destination, where they try making jeans in the tropical heat.
Episode four sees the youngsters tackle a shift in a tuna processing plant, where they are asked to gut, skin and bone fish all day.
Finally, they visit a chocolate factory and school.
Accompanying the group was TV presenter Stacey Dooley, who has starred in a number of programmes showing the reality of life in third-world countries.
