The E-man himself was confused by this one, so I will not claim any =

let's start with wild conjecture before we make this into real work.
There is no reason that the iron would need to be moved to cause the =
problem. If the water aquires a "direction of flow" related to the
magnetism generated by the spinning (think drains flowing out), that =
would be enough to cause a hurricane looking crack, or an s crack. =
The water would try to exit the clay along the polarized routes it was =
headed when it began drying. An s crack looks a lot like a hurricane. =
And Southern hemisphere hurricanes and drains flow in the opposite =
direction from northern hemisphere flows. =
So what would give us some more perplexing data would be: do southern
hemisphere s-cracks run opposite northern hemisphere s-cracks.
And for that data collection we would have to hear in from some clayarter=
s
from both areas of the world. Anyone?
One experiment for s-crack sufferers: =
Try to shake up the flow-set by turning your wheel in the opposite direct=
ion
for a few spins when you are done shaping. Don't change =
anything but this aspect and see if it still cracks. =
Wouldn't that be a hoot? to try to pass down to students with no explanat=
ion
of the why, "just do it, I don't know why it is true...". =

I never mentioned the moon. One bit of pseudo-science at a time.
And yes, science-people, this is wild speculation. Pretend it is
1500 years ago and this will seem like theoretical astrophysics. I
am curious enough to speculate and think aobut it, but unwilling as =
yet to talk to a physicist (they can be rather dry and humorless).
