I must admit that as a child I used to be able to and did indeed find it a wonderful party trick. In my head I still always thought I could do it but haven't tried for a good few years. Having just tried I must sadly report that this is no more the case, my hands have grown too big. (frankly I'm heartbroken despite the fact I haven't tried to do it for years!)
sorry tine e.a for highlighting your inadequacy. and to think, a few moments ago you we're none the wiser. just goes to show ignorance is bliss! sorry again for causing upset haha!
and good effort to xhxmxsx. didn't think it'd be so soon that we had a yes! congrats!
