Video: Female astronaut in the universe

Life in space is not like what we often see in movies like Star War or Avatar, there are quite a lot of interesting things.Video synthesized by Mashable below will show us how astronauts wash their hair.

Expedition team member Karen Nyberg 36 on ISS International Station will show us how to wash her hair in a 3-minute video.

In the weightless world, your hair is either long or short standing on your head. You can't flush water in a weightless space, so if you want to bathe in the hot water of the shower you'll have to wait until you get back to Earth.

Bathing yourself in space and distributing water depends largely on surface tension, which you can see by way of Karen draining water into her scalp in the video. Most water sticks to the scalp, but you can see a few drops wandering and mutating strange, things that often happen in a weightless state.

Karen shared that she felt her hair "clean" after the end of this quick shampooing process.

Before watching this video, we thought it would be better to cut short hair before starting a journey of space travel. But after watching this video, the process of washing hair in space is quite easy, there is not much else to know whether your hair is long or short.

An interesting aspect of this video is a reminder that astronauts live in their biosphere, where steam rises from wet hair machines moistening the environment (as well as on Earth) and as Karen says. Moisture in this environment will be extracted into water and used as drinking water. Neat!
