Daredevils are hurling themselves downhill at 30mph inside giant inflatable spheres painstakingly created by a specialist Norfolk firm.
Cromer-based Structure-flex has made three 12-foot spheres for gift experience company SphereMania, which offers people the chance to roll downhill, at an adventure centre in Nottingham, inside a transparent globe; an extreme sport sometimes called 'zorbing.'
Making the spheres is a skilled and time-consuming process. Each takes:
? more than 120 hours
? 67 metres of fabric
? 500 webbings
? 1,000 rivets

Paul Reeve, managing director of Structure-flex, said a second, smaller, inner sphere, accessed through a tunnel connected to the outer sphere, was where the thrill-seeker was suspended by a harness and cushioned from the ground by about three feet of air.
A complex network of webbing straps in the air gap provided stability.
He added: 'I haven't tried it myself but it certainly looks like it's not something for the faint-hearted!'
