- The property is called thixotropism, and a substance possessing said
- property is thixotropic. This means that it changes its ductility and
- resistance to pressure depending on the speed of the force applied to it.
-
- Another way of looking at it is that it will behave like a solid or like a
- liquid depending on the time-scale in which you are interacting with it.
- Many substances are thixotropic, in this view. Glass shatters like -- well,
- glass -- if you hit it with a rock; but over centuries, panes of glass will
- start to flow and sag out of their frames. Over tens of millenia, rock will
- flow like liquid. On the other hand, water, our archetype of liquids,
- behaves a great deal like concrete if you hit it head first at terminal
- velocity off the top of the Golden Gate Bridge.
-
- In the mixture you describe, the transition from "solid" to "liquid"
- behavior is particularly abrupt, and happens within the range of
- accelerations that unaided human muscles can generate, and the range of
- timeframes that unaided human perceptions can observe.
-
- A final observation: Rush hour traffic is thixotropic.

- I have been looking for an opportunity to use the preceding sentence for
- at least two months, and you handed it to me on a platter. Thank you.
