Zorbing is an extremely adventurous sport in which participants roll inside a zorb. It is usually practised on a slope or a levelled surface. The events can be conducted on ramps, made of wood or metal. Zorbing is popular in theme parks where it is carried out on a water surface. The participants fit themselves inside a sealed orb and then start zorbing. 

Two kinds of the orb are generally used in the events, either a harnessed orb or a non-harnessed one. The inbuilt capacity of the harnessed orbs is smaller than the non-harnessed one which can carry three to four riders at one time. However, the harnessed one can only carry one or two riders at a time. 

The zorbing ball is made from two separate transparent flexible plastic layers that are connected by a hundred pieces of ropes, facilitating proper turning and rolling of the ball. The size of zorbs is bigger than the beach ball, and can easily be rolled downwards on a grassy or inclined surface with a rider zipped inside.
