Astronauts Don't Cry

The commander of the International Space Station shows how crying in space only leads to a big water bubble on your eye.

While zero gravity doesn't have an impact on tears forming, it has an effect on if they fall, and they don't. The water just builds up on your eyes and will stay there until it gets so big it moves to another spot on your face, or is removed. It's not very pretty or graceful.

Watch how Canadian astronaut Chris Hadfield, the commander of the international Space Station and maker of all sorts of entertaining space videos, demonstrates what happens when you cry in space. The tech-savvy astronaut tweeted in January that it can hurt to squirt tears in space, since they "don't shed."
