This adventure activity was invented by Dwayne van der Sluis and Andrew Akers in New Zealand in 1995 as something exciting for tourists to do once they became jaded with bungee jumping. They created the term Zorb for the ball, presumably a variation on orb, which they trademarked and which they used for the name of their company. Variations are becoming known, such as hydro-zorbing, in which you are drenched in soapy water on the way down (the nearest thing in existence to a human washing machine), and harness zorbing, in which two people are strapped together. On flat land, a number of participants can play bumper-zorbs. A participant is often called a Zorbonaut.
The Guinness Book of World Records recognises two sphereing records, set over two consecutive days in 2006:
-Longest sphereing ride held by Steve Camp who travelled 570 metres (1,870 ft).
-Fastest sphereing ride held by Keith Kolver who reached a speed of 52 kilometres per hour (32 mph).
-Fastest 100m in a Zorb – 26.59 seconds. Held by Andrew Flintoff who broke the record as part of his attempt to break 12 world records in 12 hours for BBC Sport Relief
