I saw this and had to share, this is fascinating. Astronaut, Karen Nyberg, no relation to me, demonstrated a while back how you wash your hair while you’re flying around in outer space. I never gave this much thought until I saw this video flip pass me on Twitter. I stopped and watched the whole thing. It’s pretty ingenious if you ask me how she did this. It’s worth the few minutes to watch this and how she actually uses water in zero gravity and then how the water gets recycled on board and how the astronauts then end up drinking it. Enjoy!
