    Great metaphor. Funny, while you were demonstrating the actual luminar flow, I was thinking of the same meaning. Thanks!

    Would it still work if the speed of the cranks was increased by 5 and reversed at the same speed. Which then the question to be asked is what is the breaking point???.... something to think on.

Recently my life has been in for lack of a better term - turbulent- This video was a small inspiration for me to make me wonder again if I can methodically correct things and be the great human I know I am. :(. Thanks your a great person

    When spun 7 times, it begins to look like the rings of clouds on Jupiter. I wonder if this is the principal that has occurred? Amazing video as always Destin. :)

  52. MassiveTrackHunter

    That was a very cool experiment!! I would think setting this up to have a firmly controlled speed for the 7 turns, both ways, should minimize the striations a lot. Speed changes could cause different amounts of shear, if the ink viscosity is thinner/thicker than the syrup?

    Hey! i think that when you use your have you create variation in the rotational speed, therefore, when you go back the colors doesn't have the same shape like you started. can you try to use DC motor to rotate the handle? i think that you can have more rotations like that. keep doing videos! i'm following you for few years now and i'm exited with every video you make!

    When you add the food colororing do they have to be at different distances (between the wheel and the glass) or can they all be even?
