Two large nickeled goblets are shown. One is filled with red confetti, the other with white confetti. The goblets are each covered with a lid and when removed, the red confetti has transformed into steaming hot coffee, while the white confetti has changed into milk. The coffee and milk may be poured into cups and passed to the audience. A classic effect. This set is circa 1925. Beautifully made. Plating is excellent.
