Pretty much the same formula for sail boats, or boats in general...

I know from experience that airplanes fly because of money. Lots of it.

I have never met Mr. Bernouli and when I said that pressure inside the car =
"increased" it would indeed have been more accurate to say that pressure ou=
tside decreased due to the air molecules' having to travel a greater distan=
ce, creating lift.. Fortunately the magnets' force is stronger than the li=
ft and my side curtains no longer pop out at highway speeds.

I believe that side curtains on roadsters have a tendency to blow out due t=
o increased pressure within the car, especially at speed. Mounting and fit=
ting the curtains perfectly so that they notch in behind the windshield sta=
ntions just enough to resist this force is not easy and I came up an easy s=
olution: I mounted a 1" square neodymium magnet to the front inside upper =
corner of each curtain and a similar magnet to the rear face of each stanti=
on using a small piece of angle in such a way that they are in their "attra=
ction" mode when the door is closed. The magnets are more than powerful en=
ough to overcome the pressure from within the car and yet they release when=
the door is opened.
I forget now my source but the magnets can be ordered with holes predrilled=
in their center and they are chrome-plated.

Norman,
I usually buy my own felt, a fairly thin and dense one, and cut my own glas=
s and make sure it fits rather tight, then you have to =93pinch=94 the glas=
s in the channel at the top and bottom by tapping the divider against the g=
lass where it ends.
