Crying in Space

What an interesting question! I've just contacted our astrophysicist expert Dr. Tom, and he wants you to know that it would indeed be possible for an astronaut to cry in space. Unfortunately, their tears would not fall from their eyes, or roll down their cheeks, due to the microgravity environment. Instead, the tears would cling to the surface of the eye, then pool, and would eventually have to be wiped away. As you may know, liquids act very differently in a microgravity environment than they do here on Earth. Rather than spilling into a puddle on the ground, they float in a little ball. While it would be quite fun to float around chasing your balls of apple juice or coffee through the Space Station, it's not very safe. Liquids could get into the electronics and equipment, and cause problems. It would also be just plain messy! Astronauts drink their liquids through a straw. They also have rinseless shampoo and edible toothpaste so that excess water isn't a problem.
As for crying in space...Dr. Tom says that there are too many cool things to see and do while living and working in space. What could there possibly be to cry about?!
