Zorbing is a sport where you?

Answer 1

Roll down hills inside a large inflatable ball (called a zorb or an OGO) - see http://www.theogo.com. There are two main ways of zorbing; 1. Hydro zorbing (H2OGO) where the sphere has water inside with the customer. The water makes the inside of the ball very slippery and you slide on the bottom of the ball - you do not tumble around inside. You can safely have 1, 2 or 3 people inside the zorbing ball at once to do this.

2. Harnessed zorbing (IGO and WeGO) where you are harnessed inside the ball (either one person or two people harnessed on opposite sides of the sphere). With this method you rotate with the ball and go head over heels all the way down the hill (safe inside your harness so you don't tumble.) Because the OGOs (zorbing balls) are so large (3.2 metres diameter - 11 feet) they only rotate once ever 10 metres (35 feet or so) and so you are not spun around incredibly fast. The balls reach speeds of up to 25 km/hr
