    First, the globe would have to be solid and sufficiently dense to scale.

    Then, it would have to be removed from any other significant gravitational field - such as the actual earth.

    Then, the layer of water would be as deep as about half the width of a pin.

    Then yes, it would work and the water would settle on the globe correctly.

    (I am not a scientist and have probably missed a variable or twenty in this summation)

      You’re mostly correct, but hilariously even all that wouldn’t be good enough because water behaves differently at different scales. Surface tension would dominate in a miniature model, and the water would be trying to stick to everything in a way which oceans simply don’t do

        I did think about that, but I don’t know how surface tension works. I’ll certainly take mostly correct. Not bad for an amateur who just watches physics videos for fun.
