Hey guys! no problem at all! :)
As for the multicolored splash photo it is multicolored for sure! Interesting how
many photographers have taken up to making splash photos and many are doing it
at least technically well ... and in their kitchen!! I was not so impressed by
this sample one but there is a woman and daughter team (sorry don't have website)
that are doing visually more effective photographs - also multicolored!
Bottom line with this high speed photography bit is that if you have the drop
detection and delay equipment (readily available these days) splash photos are
not that hard to make. In fact, you can probably cover all that needs to be covered
in less than 15 minutes! In academia things get stretched out sometimes!
BTW, I do need to clarify one point. I never worked in research with Edgerton.
He was a long-distance or "virtual" mentor and although in the latter part of
his life i knew him to the extent that we presented papers at the same conference,
such as the International Conference on High Speed Photography and Photonics, and
we sat and had lunch together, the most memorable lighthearted memory I have of him
is that once I got a phone call, I picked up and said "hello" - the voice at the
other end said: "hello, this is Harold Edgerton" ... who is this? - after a moment
hesitation and amazement I said: This is Andrew Davidhazy. He said: Oh, I have the
wrong number and hung up!! Another not so funny moment was following him as a speaker
at a conference. Not a good experience!! ;)
cheerio,
andy

Deepest apologies to Andy. This was supposed to go to a friend. I
overstated my remarks on Andy's seminar. He spoke about his photos
taken on a rotating turntable and gave a demo and photographed a number
of students and me. I was hoping he would discuss high-speed
photography, but I didn't give him very clear instructions on what the
students might find most useful in their research.
My friend and I once had a grant to study the effect of bursting
bubbles and the droplets thereby formed, which would fall back to the
liquid surface, generate more droplets that would hence be carried on
shore by the prevailing winds. These droplets, essentially salt water,
would then cause damage to plants not accustomed to being bathed in
salt water. Our focus was on the mechanics of bursting bubbles and the
subsequent processes as they fell back to the surface. I wish I could
say that it was successful.
Again, my apologies to Andy. The seminar was fine. If he cancels my
membership in photoforum, I won't blame him!

John,
ps: The Andy referred to is Andrew Davidhazy, a professor at RIT,
who specializes in high speed photography and who once worked in
research with Edgerton. I had him to UH to give what turned out to
be a not very good seminar. He has taken a lot of micro- photographs
of speeding bullets crashing through various objects as well as
droplets falling on liquid surfaces.

Here is a variation on the classic water drop photograph. Andy may
like this. Or not.
