When I first saw this ball, the first word that went through my mind was "claustrophobic." This ball is called a zorb and the activity called zorbing. These are actually 2 plastic balls one inside another. There are 2 Guinness records for zorbing. Zorbing is an extreme sport which originated in New Zealand. You can do it on land or water and you can even have the zorb filled with water. What's more if you don't want to go alone, take a friend or two. I don't think I would ever want to be in a zorb. But thisvideo on U-tube makes it appealing visually what with the nice greens and the cheerful music in the back ground. Have any of you been in a zorb? Did you like it?
