According to the authority of NASA, the issue of surface tension and capillary effects were defeated by Earth's gravity. As a result, the coffee liquid is in the glass tends to stick to the glass wall. But now coffee mug "zero-G" can overcome this problem is to flow with the current. How it works by utilizing the anomalous properties of liquids in micro gravity.

In an interview with Marshall Porterfield as the director of the NASA Space Life and Physical Research and Applications Division of Portland State University revealed cups are specifically designed to take advantage of the style in space and allow coffee to be consumed.

"With it, we can make a cup large enough to keep exploiting capillary forces so that when astronauts bring to his face, there is a gradient in the driving force of surface tension to push the fluid right into the mouth of an astronaut. The theory of basic science can also be used to help create cooling or cooling systems in space, "said Dr. Weislogel.
