Zorbing

For a truly bizarre experience, strap your undaunted friend into a giant inflatable ball and throw them down a hill....

No, this isn't because you've had enough of them going on about his/her husband or wife-to-be. It's known as zorbing and, strangely, it is catching on. Introduced by those adventurous Kiwi's, the experienced sensation is supposed to be close to feeling weightlessness.

You can have a couple of people in a zorb per run, so the rest of you can join in by having a go or even lying in the path of the approaching zorb to ensure your stag or hen has an eventful roll...
