Hold the metal cup with your hand and place around the ball with the ball near but not touching the metal. If the ball is far below the lip of the cup then the metal cup effectively shields the ball from the electric field created by the rod. Try to attract the ball with a charged rod outside the cup. Does the electric field of the rod reach inside the metal cup?
