Zorbing
The Zorb is a large plastic ball made of 2 chambers. The large outer chamber wall is in contact with the ground and is linked to the inner chamber; supporting it within the center of the outer sphere.
The inner chamber is where you ride this huge ball down hills at speeds of 30-50 km/m with a bucket of water; this is called the Zydro.
The Zorbit straps you into a harness and you go down the hill head over hills until you reach the bottom. I really don't want to mess up the Zorb so I will go for the Zydro with Tegan as my travel buddy.
Prepare to get wet!
