    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.

    Now the question to ask would be: Is there a number of cranks in the forward direction that could also see it eventually return to its original state.

      Nope, because you're just spreading the layers thinner with each crank. I think anyway..

    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

    BUT....technically there was no mixing of the colored corn syrup. Right? It was just an illusion of mixing becausse they were spiraling on top of each other?

    • party4lifedude
      party4lifedude 4 days ago

      they never really touched but if you looked at it from the side you are looking through all 3 layers so it filters the light as if they were mixed.

    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.
