A dissolution phenomenon of carbon dioxide into water is visualized. The authors employed solution of calcium hydroxide to detect carbon dioxide. Chemical compound (calcium carbonate) visualizes behaviors of carbon dioxide rich water. Since rate of chemical dissolution is larger than the rate of physical dissolution, it is easy to observe mass transfer phenomenon at the gas-liquid interface. High resolution video camera (1024 * 1024 pixels) and back lighting are used for observation of the interfacial phenomenon. In a top view image of the interface, the pattern exhibits a structure composed with many small cells. And also in the side view image, many slender strings slowly stretch and sink toward downward
