Teen tycoons from Tapton are set to have a ball in Berlin after scooping the top prize in the seventh annual BiG Challenge.
The team from the Sheffield secondary came ahead of over 400 teams who applied, containing 1,200 eleven to 19-year-olds from across the city.
Each team was given a £25 investment and the five Tapton Year 9 youngsters managed to increase that amount by more than tenfold.
Their business Aroma Blossom produced and sold handmade candles, soaps, bath bombs and body butters made from natural, vegan and eco-friendly ingredients.
Team member Lucy Zhang said: “Being involved has been an amazing experience. We have learnt so many new skills that will continue to be valuable throughout our lives.
“Many can only be gained through this sort of experience, not in a classroom.”
Other winners at the grand final at the Royal Victoria Holiday Inn included teams from Meadowhead, All Saints RC High, Forge Valley and High Storrs.
Chair of the event David Grey told the teams: “I believe you are growing up in a time of increasing opportunity for business in Sheffield and especially for innovative products and services. ‘Made in Sheffield’ not only means a lot because of our history – it resonates around the world.”
