Which drink do astronauts avoid?

Answer: Cola

NASA has made great efforts to produce space-friendly versions of well-known cans Food for astronauts, but there are certain delicacies on Earth that simply do not make the leap into microgravity smooth.

One of the treats that taste best at home is Coke. Carbonated colas in the form of Pepsi and Coca-Cola were first flown in 1

985 on the shuttle mission STS-51-F into space. On Earth, gravity separates the solids and fluids in our stomach from the gases. In microgravity, there is no such mechanism that keeps the food down in the stomach and allows the gas to rise up. The same problem also affects the can. Crack a cold one here on Earth and the gas immediately goes up (and the carbonated liquid comes to an end). In microgravity of the Earth's orbit, the gas remains suspended in the solution for a longer time and each sip is significantly more carbonated than on Earth.

Between drinking Coke from a specially adapted container (see picture) The approach of Pepsi and Coca-Cola to the problem), where each sip is carbonated, and the very disquieting feeling of having a large dose of carbonate in your stomach the air is chasing – in addition to the fact that it's difficult to belch because the gas does not escape from the suspension and go up to the abdomen – you can imagine why cola never caught in space. There's just no cola delicious enough to endure the confusion and hours of gasoline.

Although NASA and other space agencies have experimented with different systems and formulas for carbonation, carbonated beverages are understandably under astronauts and have since become unpopular. Experiments in the 1980s were largely unexplored in space.
