Zorbing is a recreational activity which emerged in the early 21st century. It involves rolling down an incline in an inflatable, usually transparent, double-hulled sphere made from PVC.
Zorbing originated in New Zealand as the brainchild of Dwane van der Sluis and Andrew Akers, who in 2000 invented and manufactured the spheres, which they named "zorbs", in Rotorua, New Zealand. The inside of a zorb contains several straps to keep the rider in place. Strapless models can be filled with water for an experience somewhat like a water chute.
Distribution of zorbs has since spread to many countries worldwide, mostly in Europe and also to China and Argentina.
