The RIGHT trousers! As Wallace and Gromit: The Wrong Trousers celebrates its 30th anniversary, scientists reveal how robo-trousers could work (and say they really would let you walk on the ceiling!)

It's been 30 years since beloved British duo Wallace and Gromit embarked on probably their best loved adventure in'The Wrong Trousers'. In the classic 1993 stop motion film by Nick Park, Gromit receives a pair of'ex-NASA' robotic techno trousers from Wallace for his birthday. They prove extremely useful when Gromit redecorates his bedroom, but lead to trouble when they fall into the clutches of the villainous penguin, Feathers McGraw. Although for now consigned to the fictional world of the loveable duo, experts think they could be built – and conceivably let a wearer walk on walls and even ceilings. Dr Katie Raymer, a physicist and PhD graduate from the University of Leicester, said a real-life pair would use powerful vacuum suction at the soles, just like in the film.
