Young entrepreneurs from near St Albans raised nearly £50 for charity through blackberry juice sales this summer.
A group of six friends from around Napsbury Park, all under 10, got together to plan the business model, pick the berries, make the smoothies, set up a stall, advertised the sale, and flog the product - all by themselves.
To market their stall, the children made posters and put them up around the park.
Thirsty punters who visited the stall included a builder who bought five drinks for his team.
Another visitor kindly donated £5 to the young business people.
Grace Bilantz, nine, Summer Boswell and Maya Sandler, both eight, six year-olds Eden Boswell and Max Bilantz, and Amelie Sandler, four, donated their £47 to the RSPCA.
They chose the RSPCA because the children all love animals.
