Mike,
If you have 2 polaroid sheets and a quarter wave sheet, you might
experiment with setting up the polaroid sheets crossed with the quarter
wave sheet between then, then put some glass between them - it should be
black when of uniform temperature. Then, differentially heat the glass
- even some sheet glass - and see if you can demonstrate stress lines in
the glass. I believe that it should work.
Good luck! Peter Anderson
