YOUNGSTERS in Rotherham can design an environmental idea to win £350 for their school.
Sheffield-based manufacturer Gripple is challenging primary school children to come up with the concept.
Launched online, it is the first primary school-focused initiative to encourage children to devise a product or service with a environmental benefit.
Rotherham enterprise team Are You Ready? is also working on the project. In September children will be able to tour Gripple in Burngreave.
