Pupils from an Ashton-under-Lyme primary have won an award for inventing a device designed to prolong the use of pencils.
Five Year 7 pupils from Canon Burrows CofE Primary came up with the idea to sustain half-used pencils normally thrown away.
Their holder grips the pencil from new until it runs out, allowing it to be kept even when it is a stub. The reusable device incorporates a comfy grip and is made from sustainable materials.
The team competed against nine other schools in the finals of the environmental social networking website Footprint Friends' Wipe Out Waste Awards. They had to make a Dragons' Den-style presentation to a panel of business, industry, science and environmental leaders.
Miah Chaudhry, 10, said: "It was a really intense experience. We were dazzled at coming to London and really enjoyed making the presentation."
The school has won a special unit allowing it to reduce its power consumption and carbon footprint by up to 20 per cent. WS.
