I received a replacement nectar card today. Nectar is a loyalty scheme that I don’t particularly use very much, as the merchants who participate in it aren’t very convenient. (For example, we do our weekly shop at ASDA (which doesn’t do loyalty schemes) but Sainsburys nearby at the very busy White Rose Centre always costs us £10+ more for a weekly shop, whilst Tesco is a bit of a road trip away in Batley.
Anyway, with the new cards came bumpf about a free treat. I took a look at their website and spotted something called sphereing. You climb inside a large inflatable ball, tuck your hands and feet in the straps and then roll down a hillside. I’ve seen these on the box but I didn’t realise that a whole leisure industry had grown up around it. 
There is a Wikipedia entry called Zorbing and it looks like fun as it is one of these extreme sports where you are not entirely in control, like white water rafting or even rollercoasters. This Wiki photo from a place in New Zealand (where sphereing originated) even shows a site with a Zorb lift to get the spheres back up to the top of the hill.
I had always thought of these objects as balls rather than spheres, but describing your hobby as Balling may well get misunderstood!
I very nearly called the posting title “balls to that” which was the non-verbal response of BloggerWife. Chief Shadelet, however, says “Bring it on!”
Don’t think I’d want to do that.
I’d try it, but I’d be a little worried about hurting myself. I’d bungee jump but I would hesitate at a parachute jump as I’d be terrified of breaking an ankle.
You’re braver than me on these things.
That looks scary to me! I wonder what sort of readers a post entitled “balls to that” would have attracted?
Daily Mail readers?
