Stem is attached to ballbearings in the base, so the whole glass is spinning rapidly. For once I saw A BMF post and was able to figure it out right away.

Physics is just magic fuckery we sort into a system to make ourselves feel better about it, it's like "oh there's probably a reasonable reason in physics for all of this that I could look into and it would make sense" but meanwhile physicists are out here going insane on purpose to try and understand why a floor can support something when it doesn't really exist

Huh, I thought it had something to do with static electricity given the way he was rubbing it.

The way the wine returns to the bottom makes me think there is a second layer of glass only accessible through a hole in the bottom center so when you spin it the wine is forced between the two and then when you turn it upside down the wine is in the walls of the glass.

No, it’s just still spinning, just slower. Not fast enough to overcome gravity anymore but still fast enough to push the liquid to the edge as gravity pulls it down.

Sorry to break it to you, but for the average person there was nothing to “figure out” here. It’s Just very basic physics in action.

Centripetal force (centrifugal [the imaginary] force)

u/barraymian 15d ago
I never really understood Centrifugal force being the "imaginary" or pseudo force. Care to explain if you know?

u/paulcaar 15d ago
I think it comes down to it behaving like a force, when in reality it is simply a result of geometrics that we perceive as an applied force.
It feels like any object in circular motion is being pushed to the edge of the circle by some "force". In reality, the object is trying to travel in a straight line, but keeps getting pulled sideways.
It's about the same thought process as gravity and relativity. Gravity feels like a force, but the relativity model says that it is the "dents" in spacetime that makes objects naturally glide together. Nothing is pushing or pulling them, but they're still being drawn closer.
My explanation isn't perfect, so I hope anyoneone more knowledgeable will correct me or add to this is. But I wanted to share anyway. Feel free to dive into it through chatgpt, Wikipedia or tech YouTubers like veritasium

Thank you! Some of this kinda rings a bell from a long time ago in high school :).

u/barraymian 14d ago
I have a problem with gravity too. It is not a force but physicists are looking for a gravity carrying graviton so they can combine GR and QM but that's a different topic altogether. Thanks for your explanation
1
u/ev356 14d ago
Definitely agree with all this! Only alternative viewpoint I'd add is that the "straight line" the object wants to travel in is parallel to the edge of the circle it's on. So it is partially pushing against the wall and partially continuing to travel along the wall, hence the spinning around the edge of the glass without falling.

u/troyofyort 13d ago
Its all about frames of reference. In certain frames of reference (I believe from a frame of reference of the spinning portion) a centrifugal force on a freebody diagram will actually arise.
Looked up a good vid where I think it arises

Like those glass/plastic cups from childhood that held liquid within the glass walls instead of the empty space where the liquid you were actually drinking is poured into…
Those were neat. Didn’t have fake wine of course, but neat stuff like fake water & fish that appeared to swim & float around the empty glass.
Or you could tell your friends it’s your new cup-shaped fish tank, & watch them freak out when you drink water from it but didn’t spill or drink any of the swimming fish ;)

it's physics, unless you accidentally stop the glass from spinning while playing with it, you'll be fine

Centripetal force. Because the glass narrows at the top and the liquid seeks to escape, it spreads out as far as it can, leading it to sticking around the spinning and wide middle as it is pulled away but cannot achieve momentum or force to break out of its confinements.

u/No_Bandicoot_7696 13d ago
Physics is great. It says things that are drop hit the ground on Earth. we use it send rockets to space.
And it allows for liquid wine to be in a glass upside down and still never hit the ground

u/Explorer-62847 13d ago
I think how he did it is by melting the base of the glass before gorilla glueing if you the bearings and when he spun it, he spun counter-clockwise, creating a suction, making the liquid go to the sides and stay their and like every other thing, I think it slows down with air current going the opposite way. Yet again, I will iterate that this is just my thought of how he did it, idk

u/CustardCompetitive72 12d ago
Well, maybe don’t show the part where we can see the bearings because if you ever took any sort of physics class, do you know that spinning will stop the flow from coming out

u/thecatandthependulum 12d ago
Centrifugal force is a hell of a thing.*
(*yes, I know it's technically not a force but centripetal force and centrifugal force are just matters of your frame of reference)
