The list of amenities astronauts don't have while living on the International Space Station is a long one. But let's focus on the essentials they go without: no running water, little refrigeration, no trash disposal, and — duh — no gravity. Because of these restrictions, astronauts are forced to get a little crafty when it comes to completing the most basic of tasks. Try washing your long hair without the luxury of pressurized water, or sleeping when you're unmoored. Does the ISS even have beds? Do you rest your head on a pillow? (Spoiler alert: No, but there are "space jammies.")
Luckily, humanity's courageous space-dwelling astronauts — particularly the dutiful Canadian Cmdr. Chris Hadfield — have heard our inquiries and responded with helpful little how-to videos to satiate our curiosities. Here are some of the best:
