.....but it would be in a graduate level polymer physics class.

My daughter, the polymer chemist, told me of another instance. A company was developing a competing product to Lexan. It appeared to be a winner. Water bottles were molded from it and they looked great and no BPA component that some fret over. Then it was discovered when the bottle was heated, for example hot water, that anywhere there was a finger print the oil from the finger print caused crazing. A perfect rendition of the finger print was visible as tiny cracks (crazing). She thought this phenomena could be the key clue in a murder mystery novel.
