It is a hollow, plastic sphere resembling an oversized, black and white 8-ball. The fortunes are given by a white plastic die in the shape of an icosahedron, floating in a blue liquid, with answers to yes-no questions in raised letters on its 20 triangular faces. There is a transparent window on the bottom of the 8-ball, and then the ball is held so that the faces up, the die floats to the top randomly exposing one of its faces in the window. As the raised white letters press agianst the window, they drive the dark blue liquid to the sides, away from the raised letters, so that the letters appears as white print on a still-dark-blue background (where a thin layer of fluid remains between the raised letters). To use the ball, the user mys hold it with the window down, ask a yes-no question, then turn the ball so that the window faces up. In the window, one face of the die wull be visible, revealing the response to the user’s question. Contrary to popular belief, it it not necessary to shake or jostle the bll before turning it, which can consequently create air bubbles that often visually distort the answer. Come with a keychain for easy and convenient carrying.
