“POPAPY” is a postcard that turns into a three-dimensional popup card when it’s heated in a microwave oven. The card is covered with a special heat shrink sheet and thin, microwave-safe aluminum foil strips. The aluminum absorbs the microwaves and transmits the heat to the heat-sensitive paper sheet, which then begins to shrink. This is what causes particular parts of the postcard to bend, stand upright and produce the 3-D effect.
