I’ve had a posts here and here recently about the Zero Gravity Cocktail Glass from Cosmic Lifestyle. Here is an interesting NASA video with Dr. Mark Weislogel of Portland State University about the development of these types of beverage holders, as well as pipes and other fluid flow hardware, that use capillary forces to provide easier and more practical use in weightlessness:

NASA Commentator Brandi Dean talks with Dr. Mark Weislogel of Portland State University about a new experiment on the International Space Station to test a drinking cup that will work in weightlessness. The Capillary Beverage experiment applies recent findings about capillary flows and surface tension and their impact on fluids in microgravity to design containers that mimic the role of gravity and should provide station crew members with the ability to actually drink water or coffee or other beverages rather than sucking them out of beverage bags with straws, as they do now.
