For thrill seekers searching for something even more extreme than harness or aqua zorbing, this head-spinning adventure in Nottingham is sure to impress. The idea is simple - head to the top of a hill, get strapped into a giant PVC ball together and brace yourselves while spinning at speeds of up to 30 mph, in the dark! After a safety briefing, clamber into the zorb and hold on tight as the lights go out and you experience an adrenaline thrill like no other - who has the stomach for it? Only the brave need apply
