Budding entrepreneurs from a host of local schools battled it out in the finals of Young Enterprise at County Hall.
More than 100 secondary school pupils made up of nine teams took part in the Worcestershire and Hereford finals.
The 16 and 17-year-olds showcased their products on trade stands around the council chamber and then took to the floor to pitch their business idea.
Catherine Driscoll, Director of Children, Families and Communities, who spoke at the final, said: "I was hugely impressed by the high standard of businesses founded by the students.
"They worked extremely hard and it was a pleasure to see all the fantastic products being displayed at County Hall.
"Young Enterprise is a wonderful programme which sets up young people with lots of skills that they need when they leave school."
Chair of Young Enterprise South Worcestershire, Paul Moult, added: "The skills they get at Young Enterprise will set these young people up for whatever degree they decide to go for when they leave school or whichever path they take.
"It gives them an insight into what it's like owning your own business.
"Young students who do Young Enterprise are three times more likely to set up their own company compared to students who don't do the programme."
The overall winner was Dynamic from Malvern St James School. They produced a book on mindfulness.
In second place was Hidden from Tudor Grange Academy in Worcester. The team designed tee-shirts with an anti-bullying message.
The judges were impressed by the themes, boldness and topicality of the products chosen by Dynamic and Hidden which led to their successes.
The Young Enterprise event is sponsored by Worcestershire County Council's Connecting Schools and Business programme.
Team Dynamic will now battle it out at the West Midlands finals being held on June 15.
