A round glass disk is used to foretell the future. A playing card is selected from a deck of cards. The spectator thinks of the card and then breathes onto the crystal. The image of the selected card appears on the surface of the glass!, then it slowly fades.
Nothing is visible on the glass, yet the eerie specter can appear at will.
Glass disk measures 2 1/4 in. x 1/4 in. Comes in protective vinyl case complete with a variety of effects and presentations.
