Celebrating the hidden heroes of technology
Where might you expect to find a paperclip, a clothes peg, and a teabag? Probably not in a museum where the other exhibits chronicle the progress of science and technology.
But those items are amongst the stars of a new exhibition at London's Science Museum.
Hidden Heroes celebrates the everyday objects that we take for granted - products like the paper tissue, the egg box, and the zip fastener - and tells the stories behind their invention.
The BBC's technology correspondent Rory Cellan-Jones went to have a look.
