Inventors showcase their weird and wacky devices

THEY say there’s a gadget for just about everything, from boots which detect radiation to a kangaroo tail for weary humans who’d like a rest but can’t be bothered to sit down.

These and a thousand other devices went on display at the world’s biggest inventions fair, where exhibitors from 45 countries showed off their weird and wacky designs in Geneva in the hope of attracting investors or buyers.

Peyman Sarhadi of Iran showed off his “super smart boot”, which he hopes will become the Swiss army knife of footwear.
