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
Now I'm wondering what high surface tension oceans would look like.
How high? Like we can walk across it high?
I'm thinking where you could lay down next to the water on the beach and have the surface of the ocean slightly higher than the tip of your nose.
Probably absolutely terrifying, considering the water would cling to you and it might be impossible to escape the surface tension.
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.
