Zorbing

Zorbing (or Sphering) is a fun recreational activity which consists of rolling downhill inside a large sphere (or orb), that is usually made out of transparent plastic. Zorbing is usually done downhill, on a slight slope, however sometimes people use flat surfaces to allow for more control and at their longest, runs can last for up to half a mile. When there are no hills around, Zorbing enthusiasts sometimes construct small ramps so that the sphere can get started. These ramps can be inflatable, wooden or even made of metal.www.leisurematters.com
