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

very regularly. The beads of water act like miniature magnifying
glasses, 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.
