I've been wondering about that ever since I saw that cartoon in our paper. Can
the "slink" rate of a slinky vary much? At all? What factors control it? If
you cut rings off of a slinky in half, does the remaining bit slink faster or
slower than the whole slinky? Does the height difference of the steps matter?

Seems like there's a bit of a physical pendulum effect happening as it "goes
over the top" to head for the next step down. Then, perhaps, the spring
constant might affect the "ooze" rate as it transfers rings from the high
step to the low step.

Sounds like the basis for a sure-thing NSF grant request to me! Now, if only I
had the time....
