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.
