    If you ran an electric current through a copper tube filled with ferromagnetic fluid could you produce a larger induction coil with a bigger magnetic field? Or solid copper coil makes most effective induction field? Can you do induction heating in a vacuum?

    Have you checked out the laminar flow used to make our plastic money here in Australia? The flow is over air, making a huge bubble which is liquid at the top and ‘solid’ at the bottom-from what I can see on videos online.

    makes an awesome demonstration of air flow as well ... and for those who think fluid dynamics and air flow arent the same ... you are so very wrong ... they are exactly the same ... they just have different viscosities and so react similarly but more pronounced ... this is why drag reduction works in wind tunnels and water tunnels ... it is essentially the same thing with different densities

    Sorry, but it's NOT reversible mixing. The colors aren't actually being mixed, they're just being overlaid in a tightly-spaced spiral pattern. If they were actually being mixed, you wouldn't be able to separate them again by simply reversing the crank.

    One thing, you have lost count during both the rotation during the experiment was conducted and they were co-indentally cut off each other. And the second thing, it was a good metaphor you mentioned and was perfectly timed to the coloured corn syrup to get back to their places by the end of it in relation to the metaphor as well. Nice video. Well done.

    Destin, I was really shocked by this video. When you pointed out the shear thinning in relation to this radial motion it very much reminded me of how the current geological formation theories are so very flawed. There's some research from a few outside-of-the-box university professors that are forging new channels of thought in planetary formation based on planets being shells with essentially hollow cores - your video here really threw my eyes wide open at how valid and plausible this research actually is! Their work goes further than anything else in current acceptance to properly explain earthquakes and various other phenomena we don't fully understand. Great video!

      ​@Crypto Nein Every statement you made here is wrong at many levels, i can dissect them and then feed you their faults but why waste time over someone who lives like a troll. Physics and other sciences are not stagnant but very much blooming and expanding in different direction. It is only when you associate yourself with researching world you come to know about them. All the discoveries at the start of the 20 century are time tested and very much established while the recent findings cannot be given the status of established science until they are repeatedly falsified or proven to be correct which takes a plethora of time and then being printed on school text books such that stubborn trolls like you can know how world works. I myself do not hold scientific dogmas in high regard but whenever we want to prove something we are burdened to produce evidences contrary to mainstream paradigms. Shifts in thinking can only occur when you have potential to overturn how and what is already known.

      @Crypto Nein ​ @Crypto Nein First of all your use of nonsensical jargon and barely expressive sentences is the real indication of being ignorant, intolerant, uneducated, conspiracy propagator, and being very daft in manners and possessing the demeanor that of a spoiled teenager. 'Overwhelming' is pretty vernacular and often used in everyday life. I very much expect such things from a person like you who interjects "lol"; "cool"; and other nonsensical words after every idea their brains can muster after drastic struggle. I think i showed real humility when i asked for your guidance in knowing the faults in geology (hope you know what those are in geology too). Instead of telling me what those faults are you started acting like a troll by insulting and criticizing me without anything to offer. Second ; English is my 3rd language and i think taking my typing skills as an insult to your intellect are very distressful. I'm researcher in Geology so it can be taken as my sincerity that I asked for your no-where to be found knowledge about geology. I'm ashamed at the capacity people tend to have to shun established sciences in favor of junk sciences. Last but not the least I very much hope that you are not from India, If yes then everything can be explained and understood regarding your netiquette and online behaviour

      @Asrar Sultan your closed mindedness and inability to research is sincerely disturbing. This kind of a damned paradigm here is primarily why we are in a stagnant state in physics and many of the other sciences. The discoveries that are being made today are actually minuscule - but not because we know so much, but because people start to believe in this kind of dogma. I literally can give you names and their institutions, but what good would that do you or anyone else who relies on the mega-teat of "MSM" and it's subjugate MSS as you refer to? Your use of loaded words such as "overwhelming" is a red alert for those who think and reason. You use a few of these phrases that reveal true intent. If you could simply recognize that humility and a recognition of not knowing is the foundation of science itself, then tremendous growth could be achieved. Please also consider the time tested axiom about flies with honey and vinegar.

      one should rely more on mainstream and less on fringe research until fringe is brought into the fold of mainstream via overwhelming scientific evidences. What we have currently is the best we got to explain geological phenomenon including earthquakes, though i support the idea that everything can be improvised until perfection. I don't see much flaw in our geology, Would you be kind enough to hint me about some so that it acts as an eye opener for me as well.
