If you are looking for an extreme sport that's carbon neutral, then why not try sphereing?
Sphereing is a new extreme sport that's growing rapidly in popularity, where people are rolled down steep hills inside 12’ inflatable balls. So if you have ever wondered what it's like inside a washing machine, this is the experience for you!
You and your chosen victim are strapped facing each other in the harnesses inside the ball, before rolling off down a hill at speeds of up to 30mph.
The general reaction is to laugh hysterically as you descend the hill, rolling and bouncing! It makes a great fun gift to give someone for Christmas, and one which you can enjoy too.
And don’t worry, with a safety harness, and 3-foot of air between you and the ground, you’re entirely safe.
