Well unless you are the proud owner of a 12ft inflatable ball the only company in Scotland to offer this activity is Nae Limits, based in Dunkeld, Perthshire.
For added kicks you can sphere with a friend (a particularly close friend, given your intimate proximity for the duration), or try aquasphering- basically the same thing, with a couple of buckets of water in there alongside you.
Cold water also, allegedly makes for the perfect hangover cure.Sphering is a great family activity - no previous experience is required, however, this activity is not suitable for anyone who suffers from epilepsy or blackouts.
