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:

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!'

Structure-flex, which employs 76 people at its Holt Road factory, has made heavy-duty flexible fabric products for 45 years and won a Queen's Award for International Enterprise in 2013 for increasing its export sales by more than 250pc over the previous three years.
