Chris Hadfield demonstrates how astronauts wash their hands in zero-g

2013-01-30 - During a video link with His Excellency the Right Honourable David Johnston, Governor General of Canada, who was accompanied with 200 grade school students from Ottawa, CSA Astronaut Chris Hadfield demonstrates how astronauts wash their hands in the weightless environment of the International Space Station.

As of today, Hadfield is one of the most important people on the planet. He has creatively been calling attention to the importance of space exploration. He's gone out of his way to make more young people aware of what it's like up there. For him, it all started on the day of the Apollo11 Moon landing. And, perhaps for the child who will grow to be the first human to set foot on Mars, simply seeing Commander Hadfield perform Bowie in space will be the spark that gets their attention.

Thank you Canadian Space Agency & Chris and the other Astronauts for all the work you put into these videos. I'm from the UK and 41 years old, but watching these videos in awe makes me feel like the kid who played Astronaut once again, even though it was 35 years ago.

Chris Hadfield is my favourite Astronaut by a long way.

I have a question how do you use toilets

[Hwkeye]

This is such a great man! Way to go Commander Hadfield!

That one drop of water floating on the left of screen is totally distracting, but totally worth it. At first, it almost looked like a small metal bracket because of the background reflecting from it, giving it a black-metallic look.

I like the way he just lets go of the mic to let it float so he can use two hands.

[slay.]

I just want to know if the signal in space is very strong or not... Heheheheh

[celticela]

the coolest thing is about what he told about the water, "we let the towel air dry and the ISS filters the water out again so we will use it again", that's maybe the best topic for Recycling system ever made! great things we on earth just don't think or don't care about :)

[flyersboy]

My dream is going to another planet and with the advice you have given me through these videos I will strive to be a better person, make better decisions and be healthier in order to achieve my goal. Thank you Chris hadfield.

I have a question, if you are somewhere quite wide in the station, and you are floating in the middle of it, not moving, and you cannot touch anything that is around you, that means.. you're stuck ?? x)
I mean, you cannot move until someone come and gets you out ??

[Shadowdreamer]

What's that little thingy floating around in the back?
You can see it in the beginning of the video.

[cloutgreenz]

He is the coolest guy I would say in the world but you know

[nikkisix]

XD 1:30-40 the little ball of water floating happy like on his left lol

[boahneelassmal]

that tiny bit flying around in the background kinda scares me :D

[divisioneight]

Nice thing about zero-G is that you can juggle things like having a third hand.

1:36 water drop floating... Did anyone observed it?

[perkypokey]

I have 2 questions. First, suppose you are tumbling through space end over end, and your eyes are completely closed so there are no visual cues to detect your movement...would you even know that you are tumbling, or would you feel as though you were completely still? And second, is it possible to stop yourself and remain in a fixed position, or will you just remain tumbling end over end for eternity?

[Maltorfitz]

It's because of the surface tension of the water. The water molecules have cohesive forces between them, meaning they all attract one another when close enough. The water forms into spheres because that is the most energy-efficient form: The average distance between the water molecules is minimized, so the attractive forces have as little work to do as possible, meaning the potential energy of that whole glob of water is the lowest it can be (or it least it's trying to get there). This is good.

Did you know that your body has its own gravity?
