Polarizing sheets: Edmund Scientific. 17" x 39" gray Q71-939 $66.95 per one,
$61.80 5-10, $56.70 11 or more. Go there in person and get a 20% educator
discount....hmmmm..... guess that's hard for most of you (hahaha!!). They also
have brown and other sizes like 6" rounds. They are plastic (thick), but I use
them a lot and they work well for most demos.
