Balancing a Bottle on the Head: Get a large empty bottle and balance it on the back of the head. Then from standing, get down on hands and knees and with the mouth pick up a cork which has been placed on the floor. Then get up again to a standing position, and remove the bottle from the head and the cork from the mouth. This sounds near on impossible, not to mention a health and safety nightmare!
