Abstract
Abstract The apparatus of the invention comprises a tube which can be inserted into the ground and carries a co-axial bolt. A nut is threaded on to the bolt. Attached to the nut is one end of a cord which is connected to a ball. The apparatus is used by striking the ball with a bat or the like until the nut has been rotated in one direction sufficiently for it to have travelled to one end of the bolt.
