Crying probably isn’t on the top of the list of official experiments being explored on the International Space Station, but that doesn’t stop astronaut Chris Hadfield from demonstrating the phenomenon of human tears in space.
The Canadian ISS commander recently took time to answer a question he says he commonly receives: What happens to your tears when you cry in space? Hadfield's video demonstration will make the inner nerd in you shout with glee.
Hadfield uses a bottle of drinking water to place droplets in his eyes and then proceeds to blink and move around. He shows off this bizarre reality: Tears don't fall in space.
Check out the video to see what happens. Trust me, you’ll understand why Hadfield says that if you’re going to cry in space, bring a hankie.
The final Wallaby squad has been announced and there is no Quade Cooper, no Bernard Foley and no Matt Toomua.
You might ask why am I putting Foley and Toomua in the same sentence as Quade Cooper.
Well, it is simple really, these are the three players who played as first choice fly-halves for the Super Rugby franchises for the entire season. They are the only three players to have played more than six matches at fly-half in the season and have played more than 1000 minutes of rugby in the pivotal number 10.

i wonder what would happen if you took some dirty old man who hasn't seen a hard since the great depression and put him into zero gravity – nothing short of biblical i imagine
That was pretty interesting, but tear production is much slower and flows in a different direction, not to mention blinking action. Now as I'm sure he has cried for one reason or another and this experiment is similar to crying, but I'm also sure that is more fluid escape (i.e. tears escaping into the atmosphere) with real tears.
Amazing! But hey! Do we call that tears when they are not produced by our body? Is it possible that our tears would find their ways going through inside our bodies and disappear before they’re full of our eyes when we cry in space? Well, are astronauts usually told by the doctor that they’d better drink more water when they’re in space? And by the way, do astronauts have their different special beds and covers in ISS designed by the scientists so as to make them feel as enjoyable as they sleep at home?
I would imagine tears float around, just as the person does, in zero gravity!!
I've often wondered what would happen if one were to fart in space. Has NASA ever done a 'farting in space' experiment to see if, well, a 'big one' were to actually propel an astronaut through the ISS? I suppose such an experiment could be dangerous, especially if it were 'Mexican night'. There'd be astros farting around bumping into equipment, bulkeads and even each other. Better cancel that idea...
Gas me up Amigo!!!
that is very very funny mr. rogers
