This is a tremendously interesting question with an interesting answer,
but it seems IMHO non-responsive to Cliff's request, because it is unlikely
that HS students will figure out the right answer." [JD]

Wasn't this the subject of a nine post thread last month engendered by a nodding Hewitt? [JD didn't participate.]

Are the students in their groups allowed to ray trace?  And could it not be expanded to a lab project w/ projector light source and RBBF or lamp globe rain drops?

bc who wants to purchase a green LASER pointer to use w/ a red one to check out the above, any suggestions?

p.s. The antarctic humidity question's being difficult suggests bc has this one wrong.
