Zorb / Zorbing Edit
Roll Down a Hill in a Bubble

You’re probably wondering why it makes sense to roll down a hill inside a big ball / bubble.  This is called zorbing.  I could provide an answer for you, but you can look at what they say at the Zorb website instead:

Why Zorb?
Andrew Akers and Dwane van der Sluis wanted to walk on water. Years earlier there had been an advertisement on TV with a few people inside a large clear ball floating on water. It looked like lots of fun BUT ... a single skin ball had problems in that every time you entered or exited the ball it would deflate and need to be reinflated and sealed. The idea for a double skin ball was born. A prototype was built in the garage of Andrew’s house and lo and behold - IT WORKED! ASTONISHING! So down to the water to test it. It was kind of fun on water, but exhausting and after being blown out to sea a few times they realised it was more work than it was worth. BUT ... the same device could be used to roll down hills. This was fantastic fun, extremely bizarre, and bizarrely extreme. Some seed capital, patents, trademarks and a business plan equaled the latest adventure sport from New Zealand: Zorbing.
