If you have ever wondered what it’s like to live in space — particularly what it’s like to sleep or cry on the International Space Station (ISS) — then you probably want to know the name Chris Hadfield.
Hadfield, a Canadian astronaut and commander of Expedition 35 on the ISS, is known for taking high-resolution photographs in space of major geological features and cityscapes from his perch high above Earth. He has become a must-follow on Twitter for those interested in space exploration and, perhaps, geology. And, through a series of videos, Hadfield has also created a tour of life on the ISS, where he spends his days with five other crew members.

In one of his more popular videos, Hadfield shows what happens when you cry in space. The video, posted earlier this month, has received more than 1 million views. It’s fascinating to watch, as, in the absence of gravity, the tears float around the eye in a what looks like a gelatinous blob.
“Grab a hankie,” recommends Hadfield after injecting water into his own eye to mimic the process.
Then, there’s the question of how you brush your teeth. “We just use standard toothpaste in space,” says Hadfield, before he proceeds to give his choppers a brushing that could make even the most meticulous dentist proud. Then, he swallows the toothpaste. Because, think about it, where else would it go?
So, what about sleeping in space? The experience, as Hadfield shows, would put the mattress industry out of business if we could do it this way on Earth. Since there is no gravity, one can relax every muscle in the body and simply float bed-free off to dreamland.
Had field records many other typical daily activities on the space station, from shaving, to making a peanut butter sandwich, to making dried spinach for dinner. He also documents the effects that living in space have on astronauts’ bodies, particularly the eyes. Experiments are underway to determine why some astronauts' vision deteriorates while in space.
Oh, and we can also learn how to get a haircut:
The videos thread the entertaining with the educational, engaging Hadfield’s natural camera presence and have some fun with the edits. It’s a pretty good way to spend a lunch break.
