Did you know that: The wind shield used in the cars was an accident.
So what happened that one day Edouard Benedictus was working in his lab where he accidentally dropped a flask the amazing thing happened that the glass did not shattered into small pieces but remained intact in one piece
when he smelled it it was keeping cellulose nitrate which was in the flask the whole night.
after some time when he read the newspaper he saw that many people were dying because of shattered glass not the car so that made him remember about the invention he made and so the cars wind shield was made
Interesting .. good post
