![]() ![]() ![]() In space, with the absence of gravity, the carbon dioxide bubbles in carbonated beverages go through an astronaut's digestive system, rather than being belched out as on Earth, and may cause adverse side effects. Some experiments have been done with special microgravity dispensers for soda, but it has not been perfected yet."Įven if a microgravity dispenser is perfected, there is no guarantee that carbonated beverages will be used in space. Vickie Kloeris, Subsystem manager for Shuttle and ISS food systems at Johnson Space Center and program manager for NASA FTCSC, says "carbonated drinks currently don't make the trip because the carbonation and the soda will not separate in microgravity. This means that carbonated beverages including soft drinks and beer may become a foamy mess during space travel. The bubbles of carbon dioxide in carbonated beverages aren't buoyant in a weightless environment, so they remain randomly distributed throughout the fluid, even after swallowing. If you use too much butter, the cookies will end up flat and greasy. Astronauts must give up many of the comforts of home when they embark on space travel - privacy, the comfort of a familiar bed, home cooked meals, and even carbonated beverages are all left behind on Earth. Sugar sucks up liquid, and when those cookies bake, it’ll release the liquid and cause the cookies to spread out. ![]()
