This Harness Zorbing experience is a bit like rolling down a hill when you were a child, but faster, safer & without the grass stains. You & a friend can experience one of the fastest thrills & be sent whirling down a hill in 12 foot inflatable sphere, which is capable of speeds of up to 30 miles & hour. If this sounds too dangerous for you, dont worry; there will be three feet of air seperating you from the hard ground, & both of you will be secured in safety harnesses. Location: Northumberland (North East)
