World's first air-cleansing poem to be auctioned off in UK
The world's first air-cleansing poem, which has removed more than two tonnes of pollution from the environment, is being auctioned off for charity to help in the battle against lung disease in the UK. Printed on a specially-treated material developed by Sheffield scientists, the poem, 'In Praise of Air', is capable of purifying its surroundings through catalytic oxidation.
