It's all in the flick of the wrist. This is the season of conkers. A game between two people with the aim of striking your opponents conker.
At St Peter's church in Clerkenwell, Friday lunch time became the conker battle ground where teams fought to become champion.
I can report the girls won! Louise and her colleague were an unstoppable force to be reckoned with.
Let's hope they go on to the nationals. Yes that's right this game is serious. There are national championships!
If like me this game is new to you here is a site explaining how to play.
