This point is discussed in "Life's Matrix: A Biography of Water" by Philip
Ball ( an editor at Nature) on p. 239-240. I'll provide some quotes from
these pages. its pressure
falls to less than zero - less than that of a vacuum! Yet there is nothing
particularly outlandish about the concept of a negative pressure: it is
simply a tension, an outward pull.

One of Giancoli's texts mentioned this example of 'negative
pressure'. I think that MANY of his examples are chosen to appeal to
to an audience beyond the typical engineering/physics major undergrad.
