Autumn Leaves and Conkers.

Every schoolboy's favourite game.
The first step is to knock the chestnut off the tree. Then you have to break it open to find the lovely shiny conker.
The conker is threaded on to a piece of string and then the fun begins.
The object of the game is to smash your opponent's chestnut.
You can soak it in vinegar to harden it.

Have a good time!
