Just curious about a peculiar observation

[David N. Levy]

I think the scientific description is that it is a supercooled fluid,
that is, one which is below its freezing point but which has not
crystalized because of a lack of a nucleation site around which a
crystal lattice can form.  I think that a certain amount of energy is
required to get the process going, such as physical motion of the
fluid.  A nucleation site such as a small piece of something also
helps.  But I'm no physicist.
