Have you ever wondered how Cinderella could have walked in a glass slipper?

The story of Cinderella was passed along orally for centuries it was written down by Charles Perrault in 1967.

While doing so, he mistook the word vair, meaning ermine, for the word verre, meaning glass. By the time he realized his mistake, the story had become too popular to change, and so instead of an ermine slipper, Cinderella wore glass.
