NASA uploaded a video of Commander Chris Hadfield demonstrating the effects of microgravity on crying.
Nasa pointed out a number of unexpected problems faced by astronauts after the hashtag #astronautproblems started trending when Comedy Central invited viewers to ponder the difficulties of spaceflight.
The American space agency Tweeted a video of Commander Chris Hadfield demonstrating the effects of microgravity on crying.
“So here’s a common question, can you cry in space, do tears work?” said Hadfield.
“I can’t cry on command but I’m going to take some drinking water and put it in my eye and see what happens.
“You can see it just forms a ball on my eye. So if you keep crying you just end up with a bigger and bigger ball of water in your eye until eventually crosses your nose and gets into your other eye. Your eyes will definitely cry in space, but the big difference is tears won’t fall.”
