ลูกบอล Magic 8

To use the ball, it must be held with the window initially facing down. After "asking the ball" a yes-or-no question, the user then turns the ball so that the window faces up, setting in motion the liquid and dice inside. When the die floats to the top and one of its faces is pressed against the window, the raised letters displace the blue liquid to reveal the message as white letters on a blue background. Contrary to popular belief, it is not necessary (or recommended) to shake or jostle the ball before turning it, as doing so can create air bubbles that may visually distort the answer.
