Oh its looks like the pool's black 8 ball from the
top. However, at the bottom, there's this 'window' where you can
see random 'reply' from the ball. So what you do is you ask a
question with the 'window' facing down, then you turn the ball to
see the window, and a reply will float up inside the liquid in the
ball, and you get its 'reply'. Its quite lame somehow, but I feel
like having it. :P Like a prediction kind of ball.
