SOCIAL ENTERPRISE DAY: Frozen chicken, nappies or shopping bags - which will be the next One product?

Planning began in a London school today on the next One-branded social enterprise product which will be sold in Co-operative supermarkets.

One Difference - which sells One Water and One Condoms to fund humanitarian projects in developing countries - launched the One Big Idea competition today to find the next One product. A panel of celebrities will select the winner and profits will go to Malawi.

This morning saw pupils at St Matthew Academy in south east London working frantically on their ideas under the watchful eye of One Difference managing director Duncan Goose, who said he was 'blown away' after the morning's brainstorming.

He said he was particularly impressed by the idea for 'super cereal bars' to fund nutrition programmes.

Goose said: 'I'm blown away by the super cereal bar. There are millions and millions of cereal bars sold every day. It's a really simple idea and I think it will work really well, so thank you so much.'

Other ideas from the years four, six and nine pupils included the One frozen chicken to buy a chicken, One pens and pencil cases to fund education, One nappies and baby product packs to fund midwives, One collectable Lego that would create a house in Malawi's national colours and fund housing projects in the African country and One cup-a-soup - 'not only delicious but will give you a warm feeling inside'.

For one group of pupils the ideas came thick and fast. First they came up with a shopping bag that would fund nutrition programmes - because everyone loves fashion - which then morphed into a football that would fund school equipment - because everyone loves football - it then became a bag that looks like a football with a football inside to fund nutrition and equipment projects in schools. And, of course it would be launched by One Water drinker David Beckham.

The pupils' verdict of their morning's task was positive - most worked on their ideas through their morning tea break and their feedback forms were full of smiley faces. Budding artist, 13-year-old Lisa Ndukidi said: 'That was good, that was quite fun.'

Dawn Butler, in her first engagement since being appointed minister for young citizens and youth engagement on 30 October, said: 'I think people like yourselves that get involved in social enterprises are very, very special citizens. Don't underestimate the good that you're doing in other countries and the good that you're doing in the UK.'

The competition deadline is 12 February. See www.onedifference.org
