Abstract
A display device includes a hollow base having a slot in its top wall and a bottle simulating transparent shell has its rear opening covered by a plurality of superimposed transparent sheets having relatively vertically staggered, translucent faced dimples formed in their rear faces, their lower border interfaces opaque with these lower borders engaging the slot and the remaining borders opaque. A longitudinally slotted hollow cylinder is motor rotated in the base and a lamp is located in the cylinder so that the bottom edges of the sheets are cyclically successively illuminated whereby the light dispersing dimples provide the illusion of rising bubbles in the bottle.
