| Right, an Iceberg has ~ 90+% of its mass under the waterline.
| Water/Ice being molecules, H2O, where the single H2O molecule
| is an O-atom to which the 2 H-atoms are attached at an angle
| of IIRC ~ 118°. In addition the H-atoms can also share their single
| electron with others H's from other H2O's. This is called a Hydrogen
| bonding.
[Andro 1]
Sounds more like one giant molecule to me. Isn't sodium chloride
just a huge crystal of alternating Na and Cl atoms in three
dimensions, angle 90 degrees?
[hanson]
| Hence you can make the following allegory. Imagine your
| H2O as being elbow macaronis, at the bend the O, and the H's at
| the ends. Now you make "ice" by carefully constructing a 3D frame
| with them wherein only the ends (the H's) are allowed to touch each
| other. *** Now you place that construct into a tight fitting container
| and you measure *** the height it ocuppies. Now, you shake this
|container and "melt" that M-ice-construct so that the individual elbows
|can inter-twine *** & cram into each other by *** occupying the space at
| the elbow-bend loci too. So, now you'll see that the height will go down,
| because the packing has become denser...  just like in water where
| the liquid state has a denser packing then the crystalline ice. Naturally,
| in reality a whole lot of other phenomena keep entering the game,
| like disassociations (pH7) or IR rotational, translational etc movements
| and displacements...
[Andro 2]
Nah nah nah... That story line is no better than three navigators
coming all the way to Bayt Lahm to see a male aphid monarch
they'd never heard of, based on a single nova nobody else has
a record of.  It's miraculous. If they were so sagacious they'd
have used the GPS constellation and not tipped off Herod.

It lacks the ring of truth, ahahanson, opening up more questions
than it answers. First we lay down a layer of macaroni shells:
(((((((((((((((((((((((((
))))))))))))))))))))))))))
(((((((((((((((((((((((((
Then a layer on top of that.
Bingo, we have graphite ice, not diamond ice.
Either kind should sink in water, where individual molecules
are playing like popcorn in a microwave.

The whole spiel grows out of trying to make sense of crystals,
we are far from answering that question.

[hanson]
AHAHAHAHA.... ahahahaha... for/to Andro 1 & 2 comments:
Right, but in that case then you must become your own pasta
maker master to soak, boil and freeze'em and see whether they
taste better your way and hope you get satisfied customers who
come for repeats... ahahahaha...  .... Bon appétit... ahahahaha...
You remind me more and more of one of my favorite physicists,
                  Ernest Mach,  who hollered at Einstein:
         "That is NOT physics!... It is NOT radical enough!"
