The Zorb is a Kiwi invention: the first zorbing site was established in Rotorua, New Zealand, by David and Andrew Akers.
Inside large inflatable balls, it offers rides downhill at speeds up to 30km/h.
Zorbing is generally performed on a gentle slope, but can also be done on a level surface, permitting more rider control.
In the absence of hills some operators have constructed inflatable, wooden, or metal ramps.
Due to the buoyant nature of the orbs, Zorbing can also be carried out on water as a water ‘hydro” ride, provided the orb is inflated properly and sealed once the rider is inside.
The Luge, another kiwi invention, involves steering a 3 wheel sled down a winding concrete strip and testing techniques of speed and cornering.
