ABSTRACT:
The present invention represents a breakthrough in advertisement tools. The liquid sign uses a system of chambers and electrically powered pumps to produce a dynamic and visually appealing advertising sign. The advertising sign of the invention uses a liquid in motion contained in a front chamber of the sign to highlight the color and other visual characteristics of a beverage or any liquid product being advertised. The liquid in motion highlights and showcases any given characteristic of a product being advertised, including bubble or foam producing capacity, color, brightness, or a logo or symbol placed on the background of the liquid in motion. It also provides for a visually attractive, electrically or battery powered and affordable advertising tool which can be used indoors or outdoors in many different settings.
