The Jaffa Space Hoppers for Schools competition is now open in the UK.

As part of Jaffa's plan to get children exercising and eating healthily, the orange, easy peeler and grapefruit brand is offering £1,500 to the primary school that uses a space hopper during a lesson in the most innovative way.

A pair of runners-up will each receive £500 towards facilities and equipment.

Marius du Plessis, general manager of Mehadrin, the owner of the Jaffa brand, said: "We're really looking forward to seeing the schools' exciting ideas for using Jaffa space hoppers in their lessons."
