You can also fill it by putting a small straw or something similar that can reach the inside of the Klein bottle. Then fill it while not letting it get inside the straw. The straw allows air to escape and not prevent water or liquid from being blocked by the air in the space.

Yes, submerging is a much easier method of filling a Klein bottle. Completely submerge it, and then just turn and shake all the air bubbles out. You can get 100% fill this way just shaking the bubbles out.

Inserting a tube until it reaches the inside wall, then submerging the bottle, then sucking on the end of the tube until the air is sucked out of the bottle, liquid will fill the vacuum. If the tube is kept at the top of the air bubble in the bottle, all the space will get filled with liquid

That would work to a point but gravity would only fill it so much. To finish filling it, you would need to pressurize the liquid in the tube with a syringe or something and it may need to be submerged to keep air from replacing the volume of the tube. The opposite of a vacuum chamber.

My first thought too. So much easier, and it's something I have at home.

[@zecuse]

@@heman5954 The hose idea would still work. 1. Use the hose to push liquid into the large portion of the Klein bottle. The air will necessarily rise up through the neck until it forms a bubble on top like the 2nd vacuum round. 2. Next, tilt the bottle until the air is completely out. 3. Finally, fully submerge the bottle and hose in the liquid and pull the hose out. No more air!

[@shayanalinejad8059]

Yes, you can fill it very easily. Instead of tilting and turning, you can use a flexible hose like colonoscopy hoses and before inserting it into a bucket of water, insert the hose completely so that it touches the top of the bottle and one end has a way out, so because The air inside the bottle is connected to the ambient air through the hose, when it condenses, it can be released and the pressure does not increase and remains equal to the atmospheric pressure, and in this way the water easily fills it all.

[@gagemiller1604]

Or simply submerge it the same way its sumberged in air. May have to move it around a bit to get rid of bubbles but all he needed was a pool or tub and some water. It has volume in the same way a cup does. Idk why he needed to use the klein bottle. If anyone could explain to me why the klein bottle is actually special for this case i would appreciate that because the point of this video definitely alluded me

[@zackarysemancik5491]

I don't think you could *completely* fill it, though. Because the hose is inserted, that's some volume being taken up by the hose, and to remove it makes it impossible, I think?

[@ok.ok.5735]

Yeah it has volume it’s just an arbitrary rule in math saying any 3-d shape that is not a closed shape has no volume. Look at cooking with a measuring cup it has the volume on the side but according to this math rule a measuring cup has no volume but what happens when we put a flat 2d shape covering and defining inside and outside it magically now has a volume but we already knew the volume based off the predetermined volume measurements on the side. There is obviously a volume and those measurements on your measuring cup are not arbitrary. This is math trying to put everything into it’s own box when we all know the world is more complex then that.

[@fatcerberus]

​@@ok.ok.5735 Math generally isn't arbitrary either - or at least it doesn't _have_ to be - it's more a matter of how accurate a model you have for the physical thing you're actually interested in (and as you note, the real world is much too complex to model 100% accurately). For the measuring cup what you're calling "volume" is answering the question "how much liquid can it hold?", while the "volume" of the Klein bottle is instead about "how much can you fit inside it?" which is a nonsensical question unless you first define what you mean by "inside". For us looking at the thing, we can pretty easily make a distinction between inside and outside (and thus measure its volume), but the ant crawling on the surface of it might disagree on that point...

[@ok.ok.5735]

@@fatcerberus math is usually not arbitrary so your 100% correct and said things better then I could write myself. Here as soon as you close off that top now we can say this object has a volume and that volume will be based on standard volume of other measuring devices like a pitcher with volume on the side. This could easily tell us the volume this can hold and that can only be 1 number and it wouldn’t be 0. I’ve always understood that anything that has mass has a volume regardless of definite shape.

Also, not even that good of a vacuum chamber, since a good one would start boiling the water after due to low pressure, and would prove why using a vacuum chamber is not the correct method to fill this vessel. Also, it does have a volume, which is easily measured by submersion. His explanation of what volume is was so flawed. using his definition, a simple uncovered pot would have no volume either.

I think you can fill it up without using a vacuum.

Editing this due to another realization that you can do this underwater just to minimize the factor of air going in or do it underwater with high pressure water pump to push air out forcibly

You're kinda like almost there but also really missing the whole point of the video at the same time. The video ultimately says that yeah, 3D Klein bottles aren't actually remarkable at all because: -It doesn't have volume, but neither does any cup/any open container. Your statement about having to fill it to measure the volume is pretty irrelevant since it applies to just any container at all. And being hard to measure by dimensions really doesn't mean anything whatsoever; it's still measurable. Any cup can have irregular dimensions that make it harder to measure by its dimensions, but it's nothing notable at all. -It doesn't have a clearly defined interior and only has a single surface, but that's the same for every cup/open container. "It starts/stops at the hole." Well so does every cup. The whole reason he ends by differentiating 3D and 4D Klein bottles is to drive the point that 3D Klein bottles aren't special at all because the whole idea of Klein bottles is meant to be 4D; 3D Klein bottles are very simply weirdly shaped cups. You made both of your points while ignoring the fact that they apply to any regular cup when that's the entire point of the video.

they i learnt this recently in my 12th physical chemistry like when we talk about boundary otbo existance it could be real or imaginary whereas when we compare otbo nature it could be rigid or flexible, so when it means 'no volume' its exactly similar to saying 'imaginary boundary' but in a much complex way 🤷🏻‍♂️

If a tree falls in the forest and no one is around to hear it, there's no evidence it made a sound. Same with your Klein bottle hole.

One of the neat things about science fiction stories from the 1940s and 1950s is they explore things like Möbius strips and Tesseracts if they existed in the real world. Two of my favorites are "And He Built A Crooked House" about a house built in four dimensions. The other is "A Subway Named Möbius" about the perils of building a subway with too many connections. Other fun things about science fiction from the 1940s and 1950s is what they got right, and what they got really wrong.

The first solution I thought while watching the beginning of the video, was to use a thin hose to pump some liquid on there, place the source container above the jar, and then just wait for the siphon effect to do its job. Even after the first try with the vacuum machine, I thought of continuing on foot. It would have worked for that small bubble! Wow, having a vacuum cube is so fancy! 😂

Hello, the easiest way to fill this Klein Bottle is to use flexible hose / tube that is smaller than the opening, put the tube inside and let the liquid flow into "main chamber". As soon as it is filled with liquid, slowly take out the tube with still running liquid, doing so you will fill in the entire Klein Bottle - the easier and faster way. Bests!

If you put a tube in so you can relieve the air pressure gradient on the inside, you can just fill it normally by submersing it and keeping the other end of the tube above the surface of the liquid. The submersed air is pressurized, so it will flow out and allow more liquid into the bottle.

When they start moving backwards that means they're going around approximately once every frame of the camera recording it. If the camera's frame rate is 30 fps and the circumference of the track is 1 meter, that means they're going 30 m/s, which is like 70 miles per hour.

Because it's not a real Klein bottle, just a 3D-Representation of the mathematical 4D object. This video is misleading in that sense, even if it is mentioned at the end.

[@johnhunt1813]

It's a little different than that. Technically a physical klein bottle in 3d has the projection of one of the dimensions into the 3 other. So thin part that extends through the main shape of the vase, in a real klein bottle, does not actually intersect and make up the shape as it does in 3 dimensions. In a real klein bottle, that intersection represent direction in 2 different dimensions and so they pass by each other with a degree of freedom. Essentially, it's like looking at the shadow of a cube against a wall and saying, "a cube has six sides". Really, the shadow of a cube has six sides at the right angle. But we can't really "see" 4 dimensional shapes beyond how we can describe them mathematically. So the laws of physics weren't broken, but the klein bottle became no longer a true klein bottle, but a shadow of a klein bottle.
