powers of ten

Here's another item I'm sure I've posted before but obviously didn't catalog or code correctly for later retrieval. At any rate, I saw this short video on the powers of ten when I interpreted a science class some years back for upper elementary school students (possibly fifth-graders). I find it a useful metaphor for this notion of social metonymy that I keep trying to articulate as a means of linking the microsocial with the macrosocial and vice-versa.
