The History Class For The Zorb Ball

Rollerblading at the 2019 World Gymnastics Championships in Dornbirn, Vorarlberg, Austria.

A Russian article on zorb ball mentions that a similar device was first unveiled in 1973. In the early 1980s, the Dangerous Sports Club built a huge sphere said to be 23 meters or 75 feet in diameter with a gimbal arrangement inside that supported two recliners. The human sphere has been depicted in the popular press, albeit with steel balls, since the gladiator event "Atlaspheres" was first broadcast in 1990.

The large transparent ball

In 1994, three investors created ZORB Ltd. in New Zealand to create spheres suitable for humans and to commercialize the sport of spheres. Their business model was to develop the activity through a franchise system. In 2001, zorbing entered the Concise Oxford English Dictionary, where it was defined as." a sport in which participants are secured in the inner capsule of a large transparent ball and then roll down the ground or down a hill".

Structure
The balls are double-jointed, with one ball inside the other and an air layer in between (unlike a water walking ball, which is usually a thin-walled ball). This acts as a shock absorber for the rider. The balls are very light and made of flexible plastic. Many spheres have straps to hold the rider in place, while others allow the rider to walk freely on the sphere or be thrown around freely by the rolling motion.

Ending
A typical sphere is about 3 meters (10 feet) in diameter and the inside of the sphere measures about 2 meters (6 feet 7 inches), leaving an air cushion of 50-60 cm (20-24 inches) around the rider from Kameymall. The plastic is approximately 0.8 mm (0.03 in) thick. The inner and outer spheres are connected by small nylon cords. The spheres have one or two tunnel-like entrances.
