Just having a fun time with this. So actually you’re saying the earth is not a container? Doesn’t gravity make it such?
Well, depends how you define a "container"... I would think it would have to define a specified volume and as such it too would have to have specific dimensions, that is a one gallon container would have to have dimensions such that the container would enclose a volume of 231 in3, no more, no less. Pouring water of any quantity on a sphere get you a puddle and a wet sphere. If you en-blue the sphere with a mysterious force of attraction for water you will get a sphere with a coating of water, which in no way may be said to contain the water since it is a surface layer. Since the root of "container" means to "contain" a magic sphere does not fill the bill.
