“A poet once said, 'The whole universe is in a glass of wine.' We will probably never know in what sense he meant it, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe. There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflection in the glass; and our imagination adds atoms. The glass is a distillation of the earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of stars. What strange array of chemicals are in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization; all life is fermentation. Nobody can discover the chemistry of wine without discovering, as did Louis Pasteur, the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts -- physics, biology, geology, astronomy, psychology, and so on -- remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let it give us one more final pleasure; drink it and forget it all!” ~ Richard Feynman

When I first read that, I knew that it FELT right, somehow, but it wasn't until I read "A Rose for Ecclesiastes" by Roger Zelazny that I came to a practical understanding of that concept. I'm quite sure that you're familiar with the story. But you might not be familiar with this one. Read it and then tell me why poets are not only a Good Thing but a Necessary Thing. thinkingoutsidethecoop.weebly.com/uploads/1/4/6/6/14669432/disappearing_act.pdf

I'm not totally convinced that that's why the droplets bounce. If it were because of the flow of the liquid under it, I think you'd see a the droplets slow down and then stop when the flow was large enough to overcome the weight of the droplet, and then the droplet would start growing and eventually just drop down to the liquid in the glass. What I think is more plausible is that the droplets reach the liquid boundary (due to their weight) and are able to dump a tiny bit of water into the liquid. This makes the tip of the droplet a tiny bit less heavy, so the top of the droplet is then able to pull it back up momentarily (because of surface tension). Of course, there's still more fluid coming down, so the droplet starts growing again, becomes heavier, and the cycle starts again.

I knew someone would explain this. I've observed it for a long time and thought this would be perfect for Dianna or Steve Mould. I haven't watched the video yet and my guess is it's the low surface tension of ethanol creeping up the side and evaporating. OK, I watched it up to 1:40. It looks like the ethanol and other components of the liquid are draw up by the low surface tension of ethanol, then the ethanol evaporates away leaving a heavier, non-alcoholic liquid to fall back down as legs. OK, finished it. I was on the right track I think. Just learned that things flow from low to high surface tension and the maragonisomethingsomething effect. Thank you, Dianna. Great video.

i'm more a fan of alchemistry girl "Rather than see the present world as exclusively a veil of tears and a black prison - none of these metaphors are mutually exclusive - the great strength of alchemical thinking and the way in which it is completely antithetical to science and in fact why science has so much contempt for it, it’s because the alchemist had the wisdom to see that everything occurs in the presence of it’s opposite. It’s not either-or, it’s both-and. They called this the coincidentia oppositorum. This is the coincidence of opposites, the union of opposites. This is a great truth because I think all of us live under the rubrics of, “am I good or am I bad? Am I lazy or am I obsessed?” The answer is that it is never one or the other. It does a tremendous injustice to being to ignore the union of opposites. Now science in order to do it’s work, which is essentially a technological work and not a deep philosophical work - it’s a minor art, science, that’s all it is - it’s the art of the physically possible. But it has presumed to be the arbiter of all thoughts, all feelings and all work. My God, the hubris of Rene Descartes to divide the world into the primary and secondary qualities, and what are the primary qualities? They are motion, mass, spin and momentum. What are the secondary qualities? They are color, feeling, taste and tactility. This tells you that you’re nothing. You never touch reality; you live in that world of sense. Therefore can only aspire to the real world through some kind of mathematical disembowelment of what your own body and what your own feelings are telling you." - terence mckenna (proponent of a science which includes psychedelics, "let us play with a full deck!")

I think that the falling droplets bounces off when they meet the wine because of law of conservation of energy which is when droplets just combines with the wine the surface area of the droplet reduces hence there is a reduce of potential energy of the droplet hence increase in kinetic energy of the droplet which cause bounce at the rim of wine.

One of the really cool things about surface tension gradients is that the liquid will normally not be static (unless it's under very particular conditions). In other words, as long as there is a surface tension gradient, the liquid will be forced to flow! This can be shown mathematically by examining the directions of the stresses at the liquid interface. Though it's not related to surface tension gradients, another interesting capillary flow phenomenon is the formation of coffee rings. All the sediment collects in a narrow annulus, because the fluid at the boundary of the puddle has more surface area, thus evaporating faster. The fluid from the inner region flows out to the perimeter to replenish the lost fluid, as the outer edge is basically pinned down due to adhesion and the puddle won't shrink. So this drives the sediment to form a ring.

“Why are you researching this, why is this important?”… Sounds like flat Earth talk to me. My first guess before finishing the video would be something to do with the alcohol and evaporation, well did I get it correct.

It's actually about surface tension gradients, but alcohol evaporation helps to power it, yes.

Thats really interesting. When testing wine and talking about qualities of the wine, one usually doesn't just wait for the "legs" to form by Marangoni effect. Usually, one swirls the wine, causing the residual wine to drip down the sides, in "legs". We've always thought that the longer those legs run down the glass, the higher the residual sugar content in the wine, since dissolved sugars increase the viscosity of the wine. One can see this in the difference between ports (high sugar) and zinfandel (lower sugar). While the alcohol contents are slightly different (port is ~19%, zinfandels ~16-17%), the residual sugar contents are WAY different: an old vine zin has 3-5g of sugar per liter, most ports run around 100-150 g per liter. Consequently, the legs last way longer in a port than a dry wine. The difference between different wines can often show up as well in legs that are more or less persistent. Incidentally, this formation of legs doesn't say anything about THE quality of the wine, rather about A quality, namely, the residual sugars. This can tell enthusiasts whether the grapes were likely harvested late or early, what type of grapes might be in a blend, etc. But given this interesting work here, I guess it also tells us about the potential alcohol content. One might guess that the sugar content will also have an effect on the surface tension gradients formed to make the Marangoni effect.

The Same thing happens when the water tension is stronger than the weight of gold dust . In simple terms it will also break when you add a drop of liquid soap to break the surface tension but instead of the gold dust running off to the sides it will drop straight down .
