John, cal ME 'Slo' but what did you mean by that?  Did you mean iron
will not sink in 'glacier'?

Our Claire is in Antarctica now camping out a few hundred miles from the
pole on the Reedy glacier collecting rocks for her doctoral research.
As she is literally SURROUNDED by water, we sent an emergency cable to
her to see if she could spare a few minutes for a little physics study.
She reports that, as far as she can tell, under NO circumstances
whatsoever does iron--whether released gently or otherwise on the
surface of water--sink.
