Zorb, Zorb Ball, Zorbing ball. Water roller The sport can be enjoyed by most individuals between the ages of 12 and 60, as long as you don't mind being strapped in and tumbled around. You are actually quite secure inside the inner capsule because all the actual rolling/bouncing is absorbed by the larger, air-cushioned outer capsule. As you tumble head over heels, the build up of centrifugal force keeps you pressed hard against the inner plastic wall, so it's easy to feel a sense of weightlessness as you enjoy the revolving view outside. 3 mtrs diameter Commercial standard Harness included Blower included Shipped direct from factory 1 weeks delivery Unlimted supply 65 kg in weight plus blower seperate package and kit bags
