Conclusion in space can make quite strange things in the human body that are wrongly adapted to life without gravity. It can cause a great deal of health problems, maintaining cleanliness is a huge problem and doing what is really unfortunate.
But is it true, as snapple caps claim, that you can not shave?
This is a question a Twitter user presented to former ISS commander Chris Hadem at the end of last week, and he received a surprising answer: it's true, a bit.
You can not shake in the universe – at least not like you here on Earth.
"You can not move in the universe because the air, food and fluids in your stomach are all floating together like dense bubbles," Hadfield responded to Twitter.
"If you met, you climbed into your mouth, so guess where the air gets stuck?"
Of course, air can travel from your stomach and out through your mouth in space. The problem, however, is the lack of gravity. Here on Earth, when gas is stuck in the stomach, it rises to the top because it is lighter than food and gastric juice.
In a universe where there is no gravity, the gas does not rise to the top. It will interfere with all the other substances in your stomach – like the video below – an ISS experiment that involved putting the effervescent tablet into color water.
So if you want the gas to come out of your mouth, it will bring with it other things. It is a sort of cross between the burp and the spew.
"When one collapses in space, it is often a" wet burp ", which means that some liquid is released," NASA engineer Robert Frost explained in 2016. "It's like acid reflux."
And in 2011, Charles Bourland, a consultant for NASA's Food Technology Center, commented: "If you rock in the universe, it's usually wet, because the fluid and gas do not break in the stomach as it did on Earth."
This somewhat unpleasant experience was also called a "bomber" that should give some idea of how terrible it is. Imagine it happened in a suit.
There are other issues. You do not necessarily need all the gas that goes to the other end. The space station is a small, enclosed environment and can therefore get quite stinking.
In the 1960s, scientists tried to find out which diet would bring the smallest fingers, because – to wait for it – flammable rear gas was considered a hazard in the pressure cabin.
Beans and other high-phytosanitary foods such as cabbage and Brussels sprouts were subsequently removed from the "Space Flight" menu, although green beans and broccoli are now included.
And there is actually air circulation on the ISS to astronauts suffocate their own exhales of CO2, so farts get moved also away.
If you finally end up with space, it was one business astronaut who found a way to move without harassment. According to the book What is it in space? Ariel Waldman, NASA astronaut and physicist Jim Newman, who spent 43 days in space, developed what he called "push and burp".
"He found that by pulling the wall he can create strength instead of gravity that keeps food in his stomach and gives him a short chance of releasing gas without consequences," wrote Waldman.
Astronauts are definitely brilliant people.
