Sphereing which is also known as Zorbing is, being placed inside a big plastic ball that rolls down a hill. You can be harnessed in a zorb or non-harnessed.
History
The first site which was available for Sphereing was in Rotorua, New Zealand. Sphereing started around the 1980s and since has been slowly becoming a very popular extreme activity to do.The zorb which is the name of the ball used, is double skinned which means one ball is inside the other and air is between the layer. This acts as a shock absorber for the person while inside the ball.
Types of Sphereing
The two most popular types of Sphereing are:
Harnessed Sphereing
In this one you can get up to speeds of 30mph, it gives you a great thrill if with you like doing extreme activities. You are strapped in, on your shoulders, hips and feet and just roll down on a hill, this may give you a stomach-churning thrill. The experience can last up to 15 seconds though it depends on the course type and how long the hill is.
Aqua Sphereing
With this type of Sphereing there are no straps required, so you just move freely along in the zorb. In this zorb there can be upto 30 litres of water so you will be nice and wet. (Tip make sure you bring spare clothes!!) In the zorb itself you will be sliding about in the zorb so it can make you feel like a washing machine. Aqua Sphereing sounds more extreme but actually it is less intense than the Harnessed Sphereing.
