There is a school of thought that suggests that "beading" of water on a

focusing and intensifying the sun's energy, burning through the wax and
paint and permanently burning any dust or dirt into the surface. The wax is
sacrificial and does not last very long.

File this under learn something new everyday.

I just read Wayne's post about sheeting water on his racer and your
post on optics.

Here's my question - what makes the water bead? Is it that it clings
to the surface, or because it can't cling to the surface?



Hydrophobic interaction.

Harry,

There is no doubt about it, you are much smarter than I am. I am
curious why a really smart guy like yourself, living in New Haven, with
some of the best schools in the country within 150 miles, would have to
slum it and go to a 4th tier school such as University of Kansas?

You did know that the really good schools provide scholarships and
grants for the overachievers. My high school counselors tried to make
sure all the college bound students knew all the options they had.

Did I tell you my Dad was on full scholarship and graduated from Yale
(courtesy of the war dept.) and my son got a work study program at
Columbia. I try not to talk about myself, so i won't tell you where I
went to school.

You seem to be working extra hard to convince me you are some sort of
worthy human being. You're wasting your time. I concluded several years
ago you were a turd, and nothing you have done since has made me
question that conclusion.

I don't believe you knew your father, and if your son (or the boy you
think is your son) is on a work-study program, it probably is the
offered by the Georgia State Prison System. Or not. It doesn't matter to me.

You missed the most important part about what made you go to the U of K.
I would have thought you could have gotten into something better.
My daughter is slumming it at state school, but she is at U of Mich.

Hydrophobic interaction.

Yup. There is quite a science associated with this. We built high vacuum
processing systems that ionized gas (plasma) and bombarded the internal
walls of bottles -- plastic and glass -- with energetic ions. The process
super cleaned the surface and water would sheet, rather than bead.

Some well know beer companies use this technology.

I always got a kick out of people who wear glasses and pay big bucks for a
"scratch resistant" coating on plastic lenses. The coating is actually
called a hydrophobic coating and does absolutely nothing to make the lens
surface "harder". All it does is adds a bit of lubricity to the surface so
dirt or dust will tend to slide off rather than scratch the plastic surface.

Wiping them with mineral oil will do the same thing.

That sounds like me.
Would that mineral oil affect the UV coatings?

No. Wipe it on gently and then off gently.

If you paid for a "scratch resistant" coating, you were probably also given
a small bottle of "refresher" or something called similarly. Guess what's
in the little bottle?
