Invention made by chance part - lV

There are various invention that made by mistakes but become most famous here are some of them.

Safety Glass

Safety glass also known as laminated was accidentally discovered by the French chemist Édouard Bénédictus when he knocked a glass beaker from a high shelf in his laboratory and found, to his surprise, that it shattered but did not break. His assistant informed him that the beaker had contained cellulose nitrate, a type of clear natural plastic, that had left a film on the inside of the glass. He filed a patent for his discovery in 1909, and it has been in production ever since.

Chocolate chip cookies

It's hard to imagine a world without chocolate chip cookies, but the delectable dessert wasn't actually invented untill 1930. Ruth Graves Wakefield, co-owner of the Toll House Inn, was preparing some chocolate cookies when she realised that she was out of baker's chocolate. Thinking on her feet, Wakefield decided to chop up a block of Nestle semi-sweet chocolate, assuming that it would melt & spread evenly throughout the batter. Instead, what came out of the oven was the very 1st batch of chocolate chip cookies & modern dessert was never the same.

Dry Cleaning

The invented of dry cleaning, Jean Baptiste Jolly, worked in the clothing industry as a textile maker but his discovery of a revolutionary new cleaning method was completely by accident. It was only when his maid accidentally knocked a kerosene lamp over onto a tablecloth that Jolly observed that the kerosene actually made the cloth cleaner, thus spawning the idea for the very first dry cleaner.
