Warning: If you haven't seen the movie 'Cinderella' before, be warned - there's about to be some spoilers. For everyone else, just some swift crushing of childhood dreams.
This week, a scientific study published by the University of Leicester's Department of Physics and Astronomy proved that Cinderella's glass slipper - you know, the one she wore to the ball - would have been completely unusable.
Yes, the shoes you've seen her box-stepping with Prince Charming at the ball in would have shattered the instant that she tried to walk in them - which would have made it impossible for her to move around in. (But much easier to be found, right? I mean, all you'd have to do is follow the bloody footprints. Just kidding. That's gross.)
The team determined this by making some assumptions about the storybook character and the shoes that she wore that night. To give the story the benefit of the doubt, they took down her shoe size as a size 6, the smallest of women's average shoe size range. They also decided that her shoes were made out of soda lime glass, the most commonly used glass material.
They then move into some pretty intense math before concluding that, even if Cinderella was an extremely slim girl, she would only be able to stand in her heels - not run or walk in them like she does in the story. If she were to move around in them, the heel have to be 1.15 cm - less than half an inch - which certainly wasn't the case in the fairy tale's many film adaptions.
Do you think the study is valid, or was the Fairy Godmother just that good at making shoes? How does it feel to having scientists tell you that fairy tales lie?
