Educational Innovationsnope not a teacher, not even really educated   except
by my own need and invention, just thought such stuff was cool..
I am quite inquisitive and look for the more unique things in life. though I
do have a great grasp of physics  but my lack of higher math always limited
me. I am in Business Information for a career and I am trying to start my
own business restoring bugs and doing Light MFG work.

anyway. as for the tint I do think it is cumulative

as for the list,,
     well the ruling majority only answer to tires/clutch/ign/fuel/ and such
and do not really dabble wher they don't know  IMHO that is wher the
educated are lacking and the uneducated are stronger.    but that never
shows in the pocketbook or in the dental hygene.. (hope I didn't step on any
toes ) there are exceptions to every stereotype  and I hope we are all in
that group.   :)

 Dan,

I, of course, meant to say photosensitive (not synthetic). Anyway,
they do give a reasonable idea of how much UV is being filtered. The
site has much cool stuff to teach science to kids.

Question: IF my van came with 10% tint (or 90% if it's now calculated
that way) and I add 30%, does that have a cumulative affect and give
me 40%? You're the only one of 800 list members who thought the beads
were cool. Are you a teacher?
