Wherever you are on a sphere, you are always at the peak of the hump; everything curves 360 degrees around you, however gradually. The hump is commonly portrayed as being in front of the observer, but that can never the case.
Yes, exactly. I thought when you were asking about where the peak of the hump is you meant the peak of the hump relative to the glass container (hence why you said things like "100 feet from the left.") That would depend on the tilt of the container
Seeing that the ground curves in all directions, would we even be able to place this extremely long container on the ground?
Nope! Unless there was a terraformed part of land, I don't think there's anywhere on earth you'd be able to place a container like that flat on the ground
Sea level is relative to the center of the earth though, not the surface of the land. So sea level actually does have a curve
Assuming the container is flat along the top and bottom, the water wouldn't be parallel with the rim of the glass.
As far as the "hump" is concerned, it would be a constant arc. Where the peak of the hump is depends on the position of the glass container.
