- International Space Station Expedition 30 astronaut Don Pettit demonstrates physics in space for 'Science off the Sphere.' Through a partnership between NASA and the American Physical Society you can participate in Pettit's physics challenge and view future experiments here: www.physicscent...
Awesome. Next best thing to actually being there and doing it myself. I certainly would like to see more performances of experiments in micro-gravity.
Lucky guy indeed! I am addicted to these videos now
Brilliant!! Reminds me of two Spacelab fluid experiments from around 1990. One was a convection experiment, the other used sound to suspend a sphere of water. Not only did they inject tracers and air into the spheres, they were able to spin them at high speed by adjusting the frequency of one or more of the tones. The Shuttle video was intended for ground researchers to monitor the experiments. That we early NASA TV watchers got to see it was just a side benefit.
Beauty regardless of the beholder.
Don! Can you do that with ferrofluids in the ring, then send electricity through the ring or something so we can see how it reacts to a electromagnetic fields of different frequencies? And I don't know if it's possible to make a white ferrofluid, but it might look cool to see how the fluid swirls when in that erratic state. Thank you so much for spending the time on these videos, and showing us this data. I'm waving at you.
please keep these videos coming, they are fascinating
Fascinating experiments!
Fascinating. Thank you Mr. Pettit!
Looks like the atmosphere of Jupiter or Saturn. That's pretty awesome. More videos like this please.
Great series, thanks Don Pettit!
You are in space how cool is that!. Seen anything strange up there? guess a million have ask already. If you have time could you please record some space debris focus on them so they are clear then unfocus as far as you can this is just to prove a subject I have been working on it would help me out big time. Wish I was you
Why would we close our space program?
Science is the way to further our knowledge!
I'm pretty sure it has something to do with hot water expanding, the redistribution of mass and surface tension....
I second this. I would also really like to see videos of "space fire"
@ikijas I would think the amount of inertial energy combined with the size of the droplet would decide if it goes through, sticks and mixes, or bounces off. Not a physicist though so it's pretty much a guess lol.
Thank you for presenting peculiar zerogravityexperiments.
Norway
It's possibly the type - ie speed - of vibration that repels some of the droplets. What does sound do to the film?
Omg when u add the white stuff it looks like the universe spinning round or should I say Galaxy .u get the idea lol
super cool!! love it!!!
Did anyone think of using these films as lenses to make a two lens telescope? like a Kepler configuration telescope?
If you get them pretty thick then the focusing distance will be small.
yeah but water likes to absorb dirt which is hard to get off it and you can clearly see even small movement defomr its shape so it is cool idea but totally unpractical
More or less. I don't know if the ISS is clean in that regard, but I think it is. But it would be also hard because the water won't stop still on the frame for a long long time. So yeah, a little unpractical.
oh wow... that is amazing...
almost like some digital star gate effect in movies
I think you should do the same thing but with magnets. See how the lack of gravity affects the behavior of magnets.
We do what we must, because we can :D Nice video!
This video is awesome!!! Congratulations on being curious. So... why do some of the water drops bounce off??? that's interesting.
Surface tension of water film, cohesion and adhesion of water molecules, volume of water drops from the syringe.
"Hey Bubba, where's the saw-dering iron? I need it to fix the re-entry computer."
"I broke it screwing around during the thin-film water experiment."
so incredible.. I love every one of these video by Mr. Pettit. there are entire PhD's wrapped up in these expiriments. a favorite of mine, is a video called "lenses and vortices" check it out!
What happens to a helium balloon in a space ship, where does it tend to travel. (up/down?)
"Because I'm here and I can"😁
How wuld fire burn in the ISS, in zero gravity, if you take for examle an firelighter cube. Will it burn? In which direction will the flames go? There is no top.. May a round ball shaped flame? But where should new O2 come from.. ^^ thx
Bubble blowing in space must be intense.
how can fire burns in zero gravity? whether it is upwards!
@EthanNin0 New Olympic sport!!!
What was that tracer? Guanine crystals?
i love this stuff. this is the kinda shit i would do in orbit.
Ok people, I have an idea, I speak russian, english and french, I am in great physical shape, so I'm ready to go to the ISS and make all your requested experiments up there in zero G. NASA should fly me to the ISS to make your wishes come true!
It just stays there unless you push it.
There's no up or down in space.
Ok how did the water vapor from contact with the iron rise up if it is in a 0 g area
Oh wait the ventalation
In space there is no up/down. The helium balloon wouldn't go anywhere.
Lucky guy to fly above earth, technically not in space.

Fifth Fascinating
@zoozaful OMG NOOOOOOOOOOOOOOOO!!! How dare he have a piece of paper floating off camera so he doesn't trail off and sticks to topic, and so he doesn't forget the main points of what he wishes to address. HOW DARE HE!!!!!!!!!!!!!!!!!!
As weird as Don is, he's pretty rad.
What if you cut your finger? this is kinda creepy.
