Weird, was working earlier... here's a link:

The toy sticking down is probably due to the airflow requirements in the capsule. Since there is "no" gravity convection is not really a thing in space and any CO2 generated by the crew would hang around them and suffocate them. To fight this the air flow on station and other vehicles is kept high so the CO2 is removed and scrubbed. In tightly confined spaces with low air flow the crew will also have personal work fans.
Gravity is something on the order of something times 10 to the negative 3. Humidity is kept low but high enough so that static is not an issue.
I believe gravity is ruled by the inverse square law. Neutral gravity points in the solar system are called La Grange points.

Don't forget tidal pull.
No, not the moon (though that's a tiny factor, as well), but the only part of the ISS that's in true "zero-g" is its center of mass. The further in or out you go from the center of mass of the combined system, the further you are from a true free fall orbit, and that exerts a small tidal pull. It's even used to stabilize some satellites that want to have a particular aspect always facing down towards the gravity well.
Not saying that's what's happening in the video, but it's another possible cause for things to be settling in a microgravity environment.
Yes, earths gravity is still pulling on the ISS quite strongly, but the ISS station's orbit at 17,500 mph gives it centrifugal force that cancels out the pull of earth's gravity. So the ISS experiences almost perfect zero G.
When I first learned about La Grange points it blew my mind.Quote:
