Canadian astronaut Chris Hadfield continued his series of fascinating videos detailing how much different ordinary life is in zero gravity with a new tutorial explaining what happens when you cry in space.
An Internet sensation, Hadfield’s stunning daily pictures of Earth from orbit regularly go viral online, as have his videos explaining everything from how to brush your teeth in zero gravity to nail clipping to washing your hands.
Hadfield posted his latest video after tweeting that crying in space hurt.’Your eyes make tears but they stick as a liquid ball,’ he wrote. ‘In fact, they sting a bit. So — space tears don’t shed.’
To illustrate what he meant, Hadfield got a bottle of water and turned on his camera.
‘I can’t cry on command, But I’m going to take some drinking water and put it in my eye as if I was crying and see what happens,’ Hadfield said as he introduced the new video.Hadfield then squirted some fluid into his eye, which stayed there just as he predicted.
‘You see it just forms a ball on my eye,’ he said. ‘So if you keep crying you just end up with a bigger and bigger ball of water in your eye, until eventually it crosses across your nose and gets into your other eye, or evaporates, or maybe spreads over your cheek, or you grab a towel and dry it out.’As Hadfield shook his head from side to side, the blob of water clung to him.
‘Your eyes will definitely cry in space,’ he said. ‘But the big difference is tears don’t fall. So grab a hankie.’
Canadian astronaut Chris Hadfield took the helm of the International Space Station on Wednesday March 13th, marking only the second time in the outpost’s 12-year history that command has been turned over to someone who is not American or Russian.
