[@MrAlRats]

I would say, an orbit is just falling without the body you are orbiting around getting in your way. When you throw an object on the surface of the Earth, the object eventually intersects the Earth and prevents it from falling any further. If there was no atmosphere and you could throw the object fast enough, it would go around the Earth and hit you on the back at the same speed you threw it (Rest In Peace). Falling/Orbiting objects mostly just keep going around the body that it is falling towards, as opposed to heading towards the centre of the body. It's actually very difficult to get anything to fall straight into the Sun to get burned up, because you would need to slow the object down a lot before it can fall towards the Sun such that it intersects the surface of the Sun. This takes a lot of fuel.

Astronaut Don Pettit invented this while aboard the ISS using some Mylar sheeting and Kapton tape. On another flight he repurposed some "spare" parts and a cordless screwdriver to create a barn door tracker, a type of camera mount that can compensate for either the Earth's rotation on land, or a space craft's orbital velocity. Using this he was the first to capture sharp images of cities lit by their own artificial light at night from orbit. Don Pettit is scheduled to return to the ISS in September for his fourth ISS mission.

[@unvergebeneid]

I love that at the beginning, the video unironically explains to you how to drink from a cup 😄

[@pierrotA]

If you think about it, it's very hard to do. You need to tilt the cup until it's too close to you nose, then tilt your head... while getting some liquid in your month, stop breathing, switch to your stomac, swallow, and start again. There is a lot of thing that we do automatically without realizing how we do it. Like walking, opening a door, drinking... Try making animations of thoses things, I'm sure you will have to do the movement at some point to "remember" how it's done.

[@SafetyLucas]

@@pierrotA If you don't think about it, its very easy to do.

[@pierrotA]

@@SafetyLucas Yes, it's the problem in space... You cannot rely on the genetic memory and the years of training. Everything is hard and need to be learned again. Obviously you do not remember, but for years you were unable to drink in a glass, walk, etc. You learn how to drink from plastics cup with small inclined opening, like everyone else. It's the meaning of my message: it *is* hard to drink from a cup, you just learn how to do it for years... And you do not know exactly how you do it, you just repeat what you learn from thoses years of training without thinking it. For someone that learn very young how to cook, program, or whatever, it feel easy... Do not mean it is.

Another problem I see with this (I may be wrong) in order to spin fast enough to make artificial gravity, you would have to spin the station extremely fast, which could cause motion sickness unless the station was really really big (again I know literally nothing about this, this is my educated guess on the subject)

When you dropped the cup, the water went up and out because of the inertia of the liquid, not because of capillary effect. Same reason water may spill out of a glass if move it sideways too fast.

[@bobthegamingtaco6073]

If it was unaffected by capillary action, it would've flown out in a much larger surface area, like a normal cup dropping

[@karlhendrikse]

The point was that it went out the pointy part, not the blobby part.

[@shawn2444]

The water and the cup are accelerating at the same rate. If the drop doesn't impart any rotation, the water and cup would experience the exact same inertial reference. Try it with a regular cup it just falls together until it stops or changes direction. The drop here isn't perfect so more water flows up than should have, however, it still illustrates the concept. As the other post said, it flows out of the pointy bit, and not the bloby but.

Inertia works on the cup and on the water the same when they free-fall. It's not because of intertia.

Actually Water Works because the lines are pressurized and constantly flowing and there are several pumps throughout a given City that maintains that pressure. That's why there's usually a boil water advisory after the water is shut off. The pressure has dropped off enough that any minor leaks in the line could allow sediment into the drinking water. Similarly, if you're ever get water from you tap that you will be consuming in some way(drinking, used as an ingredient or boiled to cook food which will absorb some of it), you should always get it from the cold tap and wait till the water is fully cold. That way you know the water is fresh, coming straight from the treatment plant and not sitting stagnant in the lines in your house or water heater.

CORRECTION: I would avoid saying "no/zero gravity" in context of the ISS, as the ISS still feels 89% of Earth's gravity, and 89% of 9.81 is more than 0. The correct term to use is 0G, they are effectively feeling weightless because there is no atmosphere to slow their spacecraft so they move (fall around the earth) at the same speed it does. They are only weightless in the frame of refference of the ISS itself.

I see a lot of astronauts wanted the cup vs the straw.

Give me that cup! But sir, it’s meant for space missions… GIVE ME THAT CUP!!

[@T1Oracle]

A straw with a one way valve works too..

[@viiking01]

now there just needs to be a perforated straw system that still allows you to smell what youre drinking! Variety is the spice of life
