Human hamster ball

Answer 1

Check out the inventors of zorbing's website http://www.theogo.com.

These guys are the inventors of the "zorb" or the "human hamster ball". They have sites where you can ride the OGO down a hill in Pennsylvania and Massachusetts, USA as well as in the United Kingdom.

They do rent the OGOs out as well, however it would be pretty expensive as all their products are commercial quality (ie very professional, strong and well built) and these products are very expensive to create - you are better off visiting an OGO site near you to experience the activity in a safe and controlled environment.

I believe they only sell the OGOs to commercial operations (ie to people who are setting up OGO sites to offer the experience to the public, or to professional promotional companies etc.)
