It is well-known that bubbles in carbonate drinks will be produced and cling onto the straw once a straw is put into a bottle or cup which contains some carbonate drinks. As the bubbles become more and more, the straw will move onto the surface of the carbonate drink, or it will drop onto the table. In order to know the characterization of straw movement (fall or drop), an experiment concerning several possible factors which may affect the straw movement was designed and performed. It was found that the time it takes for the straw in the carbonate drinks to fall and drop was affected by exposure time of the carbonate drinks, the proportion of the depth of the drink surface to the height of the glass and the straw length as follow: (1) the time it takes for the straw in the carbonate drinks to fall and drop increases as the time goes on; (2) The time it takes for the straw in the carbonate drinks to fall and drop decreases as the depth of the carbonate drink increases; (3) The time it takes for the straw in the carbonate drinks to fall and drop decreases as the length of the straw increases. Based on the results of moving characteristics of a straw in carbonate drink, an inverse correlation between CO2 capacity and the time of straw to drop (or fall) could be deduced, and together with the results mentioned above, it is possible to estimate the CO2 capacity of some unknown carbonate drinks by comparing the time of straw to drop (or fall) with that of a sample with standard CO2 capacity, the most important detective index of carbonate drink. The phenomenon observed in this study may provide a novel idea for the rapid detective method of CO2 capacity. Introduction Different kinds of sodas began to prevail worldwide with its featured tastes and flavors since the end of 18 th century. A very important characteristic of these kinds of sodas is that after opening the container, the carbon dioxide compressed in the sodas will release gradually due to the pressure difference between the container and the air outside. When people use straws to drink these carbonate drinks, they will observe some intriguing phenomenon, like: the straw will begin to move automatically as soon as letting it go, and then the straw will float onto the surface of the carbonate drinks gradually or sink into the carbonate drinks. Therefore, it is interesting to find out which factors might affect the movement (fall and drop) of straws in the sodas? It can be inferred from the feature—the carbonate drinks release carbon dioxide—that the continually produced bubbles act as an important factor. In other words, the differences showed are affected by the forces—which is exerted by the bubbles—the diversities of areas that the forces exerted on, and so on. Under standard temperature (20°C) and standard pressure (about 101.325kPa), the carbonic acid is unstable and they tend to break down as water and carbon dioxide. And because that the straw is inserted into the carbonate drinks, the bubbles will cling to the straw because of the surface tension before they became big enough. Other people have performed the similar experiments before but all of them were not precise enough. They contained problems such as the unregular shapes of the bottles, unequal diameters of the bottles, unequal depths of the bottles, unequal lengths of the straws and the imprecise performances [1-4] . As a result, this experiment concerned about the multiple factors that might affect the movement (fall and drop) of the straws in the carbonate drinks systematically and
