Hi Everybody,

I just finished ordering another 1000 diffraction glasses from Rainbow =
Symphony.=20

http://www.rainbowsymphonystore.com/fireworks-glasses.html

They are great to hand out at demo shows and even to classes if the =
numbers are right. We use them often enough to warrant buying large(ish) =
quantities.=20

Unfortunately most of their glasses are double axis gratings, which can =
be confusing for students and the public. The do sell linear 500 =
lines/mm glasses that are almost perfect for demonstration purposes, but =
they're a little spendy. In a perfect world I'd have the linear gratings =
in the hand-held style glasses ( =
http://www.rainbowsymphonystore.com/digrglhahest1.html ).=20

Here's the catch: I inquired about the possibility of having them made, =
and they sure can, but they print in sheets of 26,000 (haha). It might =
take us a while to get through those on our own. So I wanted to throw =
out the possibility of a group purchase! I bet if we bought the whole =
batch they'd sell them for maybe 10 or 15 cents apiece (or less), and if =
we had enough schools interested, we could potentially get 1000 glasses =
each for like $100! Not a bad deal for the fun they can provide. I =
intend to inquire with a few other manufacturers too.

Any interest? Stan is in Sweden on sabbatical and has some interested =
folks out there as well. I think this could be a great deal! Strength in =
numbers, right?

Till Then,
Ben Wright

BAM!=
