It's really cool to see how astronauts drink coffee in space.

Recently, during a science and technology question-and-answer session with Maryland Primary School, astronaut Jack Fischer, who is currently living on the International Space Station, answered various questions raised by students. In one of the sessions, he said: "when I was on Earth, I liked coffee very much." But in space, I need to squeeze the coffee ball out and suck it. This is really cool. "

In a subsequent tweet, he detailed how to squeeze the coffee bag, then watch the coffee liquid fly out in weightlessness, then guide the liquid to the front of the face and swallow it into the mouth.
