Ah - I see the problem here. You need to watch more Phys Vids by EK ;) The metal licks make in to quite a few of the videos. PVEK is, by far, my favorite hard science channel on this psychotic platform.
Agreed. You don't see the surface tension effects because it isn't a fluid. The blocks are supported by the lattice applying static forces anisotropically, which fluids cannot do. You can tell this because the block is neither rising or sinking. Once the surface closes over the top of the block it should sink. In the very strong force case you would expect it to be expelled somewhat.
@@BariumCobaltNitrog3n I really don't understand your argument. In one reply you say everyone should learn atomic behavior in one semester. In the next reply, you concede that atomic behavior is complex enough that solving equations doesn't let you understand the behavior in a more intuitive way.
Or the surface of each sphere if they are made of a substance that repels the liquid they’re in? Can the whole thing generate electricity? Imagine this in the tarmac of streets and in the cars’ wheels turning friction into electricity. Or such material in the soles of shoes- people charging their mobile phone when running- I reckon many would take up jogging or being physically active. I don’t know what I’m talking about, never likes maths or physics. But sometimes it’s fun to imagine stuff.
Friction is causing heat, nuclear reactors water is heated to turn turbines with a dynamo. So you would need to somehow take the heat from your shoe and send it to a turbine, really complicated and a shoe is generating so little friction that just building such a device probably takes more energy than it will ever generate @@claudiamanta1943
I suppose the "surface" thing only means it's gonna make a difference for you only as long as the effect is strong enough AND you're still above the surface. If the attraction is too weak to keep you above and you fell through the surface, you're just going to keep sinking as you normally would...
Visualization combined with a rare talent for explanation, I observe the efforts that go into these videos. I am awed by the results of the hard work. Congratulations to your narrator, to you and whoever else is involved in these efforts. There is the hard work, but also the love of your subjects. A decade of product, that I hope will inspire those at whom you aimed it. Too late for me, I am afraid, though I use this resource to clarify my muddled understanding, That much you have done for me. I am grateful. For the young up-and-comers, I hope they take advantage of what you laid out for them. They can use these lessons to forge ahead, to understand and develop further what old people like me, can no longer do.
I would like to see another demonstration with the red box, but this time with the combined effects of attractive forces, both between the balls and eachother, and also between them and the walls.
Came for the surface tension, left the vid finally understanding how liquid helium's superfluidity works after 14 years after first being exposed to the concept, as well as feeling stupid for not figuring it out myself.
@@EugeneKhutoryansky I did engineering originally (medicine afterwards). I wish we had you as our professor in the old days. We were given textbooks and told to read things up. There was very little explanation. You turn difficult concepts into easily understandable subjects.
You need to explain fluid exposed to air that has O2 and Nitrogen. Non zero force on the air liquid interface. Surface tension is more than what you said 😅
@@priyakulkarni9583 What does that have to do with the animation? I think it is a good emulation of surface tension of water in a hydrophobic flask. The animation i believe backs that because its just a simplification of the forces involved.
@@jnr2349 The presence of air at the surface of water can indeed affect surface tension. Oxygen and nitrogen molecules from the air can dissolve in water, and this dissolved gas content can influence the properties of the water surface. However, the impact on surface tension is not typically significant compared to other factors. Surface tension is primarily determined by the cohesive forces between water molecules at the surface. While dissolved gases can influence the surface tension to some extent, their effect is generally minimal compared to other factors such as temperature, contamination, or the presence of surfactants.
is 'surface' tension a bad name then since the attractive forces are consistent in the entirety of the fluid, and not just at the surface? and is the surface tension equal to the attraction force of the molecules between each other, or is dependent on other factors like density / velocity of the object coming into contact with the fluid?
So this would explain meniscus in a test tube? Oh, and it's hard to pay attention to the narrator b/c of how FIRE the guitar solo in the background is lol
@@EugeneKhutoryansky amazing, you have a wonderful way of explaining complicated things. I always look forward to your videos, you are doing humanity a good service. Thank you!
It would also be great to see a) walls with repulsive forces and 2) blocks with attractive or repulsive forces. A block that is attracted to the strongly attracted spheres would break through the surface tension. A block that is strongly repelled by the spheres would act spherophobic.
The last one is not a fluid but a solid. You've made the bonds between particles so strong that it no longer behaves as a fluid should. Not to mention that the physics behind surface tension is a little different to that of the overall bonding between particles in a substance, so this illustration is, unfortunately, a weak analogy at best.
It is interesting how to balls with zero attractive forces look like metal grains. I wonder if there is some similar mechanism occurring there. If so, then by making the particles of metal attracted to each other it would be possible to make a solid, aligned crystal structure. Something similar to diamond perhaps?

Cool video! I'd never really thought about how surface tension works! I'm curious as to whether this model can explain how 'breaking' surface tension would allow an object previously held up to sink to the bottom. It's strange how it's called surface tension when the attraction between the liquids' molecules is present throughout.. Is it stronger at the surface?
It is different at the surface because the forces from the other molecules of the liquid are not balanced out in all directions, as they are internal to the liquid.
I wrote python code which is a plug in into the simulation program "Poser Physics", which is a plug in into the Poser animation software. I explain how I make my 3D animations in my video at ruclips.net/video/6Hl5dvA88Uo/видео.html
In the animation with the box and green spheres. If the box would completely penetrate the first layer of fluid, so it's under the surface, will it continue to sink? In the animation the fluid behaves almost like a solid so I wonder. In theory the box should completely sink.
Water: moderate self-attraction and attractive wall (dip in the surface). Mercury: moderate self-attraction, no attractive wall (bulge in surface). Liquefied helium, or any "superfluid": no self-attraction, attractive wall (climbs wall). There are other combinations in the video and other associated physical scenarios, but these are the most commonly discussed.
It is quite the stretch to call this a fluid simulation. The spheres behaved much more like a solid. To get the effect you were trying to achieve you need to give them thermal motion and make them less rigid.
From 2:35 to 3:31 makes me wondering if surface tension and buoyancy could be related, because the box never fully sinks or touch the bottom of the container, hence it floats somehow.

Awesome. I always thought surface tension is such that a strong film/sheet/layer forms on the "surface" of a fluid. This is an eye opener for me
well, surface tension is a direct consequence of the attraction between the fluid's molecules - a symptom, if you will
