Rosalie, please re-read what I wrote. Don't you see the word "unlikely" up
there? I never said something couldn't happen, I said it was unlikely and
gave the reasons why. Why do you take issue with that? Can you provide one
solid reason why I'm incorrect?
Of course I've heard of eddies. Are you familiar with currents and eddies
in the Cook Inlet - which was where the original poster hit the "container"?

Right. What it will do is follow the currents, both vertical and
horizontal. But what's the odds of something being the "same specific
gravity as water"? And what's the odds of that thing remaining at that
specific gravity? Human drowing victims sink in cold water, then refloat a
few days to a few weeks later, when the specific gravity of their body
changes. Containers, which was the subject of this thread, slowly fill with
water, and unless they're filled with a lot of buoyant material, will sink
to the bottom, where they'll remain for centuries.
