1. That is AWESOME! This provides a whole other dimension to finding the rightful owner of the glass slipper.
2. I think there should be a whole series of engineering fairy tales!
3. You should start with the 3 little pigs (how much force it takes to knock down the various houses or something)
How about "The Goose That Laid the Golden Eggs" (gotta love that Aesop). A little biology mixed with heavy duty alchemy? To boot, isn't this story what Silicon Valley is all about - ok maybe I'm being a little cynical.
Love the 3 little pigs idea - sounds like great fodder for MythBusters!
What about Jack and the beanstalk, what kind of genetic engineering and mechanical engineering is required to have a plant grow as long as to reach the sky?
Not to metioned the speed and materials required to make it grow over night!
Talking about something similar, have you heard of the concept of Space elevator?
Arthur C. Clarke introduced it to the general public in "The Fountains of Paradise", although it is an idea from a Russian scientist...
The engineering analysis was tremendously fun. However, the explanation for the appearance of the glass slipper, is that it was never in the original story, which was french, and in that the shoe was made of vair, or grey squirrel fur, and vair sounds like verre, which is, of course, glass (http://www.iletaitunehistoire.com/genres/contes-legendes/lire/cendrillon-biblidcon_029).
The original publication by Perrault refers clearly to the word "verre". There is a controversy in French because author Balzac, 150 years later, proposed it could be a typo and should read "vair"... But it most likely is not the case.
