A scientist and an award winning poet, both at the University of Sheffield, have made a giant poster that uses nanotechnology to gobble up pollution.
It can absorb the poisonous compounds from around 20 cars each day if you put it by a busy road.
The 10m by 20m poster is coated with microscopic, pollution-eating nanoparticles of titanium dioxide.
Simon Armitage, who’s professor of poetry at the university, has written a poem to go on the poster. It’s called “In Praise of Air”
The poster will be on display in Sheffield for the next year.
