Casual discoveries are wonderful, and so would be thought by both the inventor of post-it notes and the inventor of the microwave. And somehow, chance had a lot to do.

Post-it, for example, were born thanks to a religious scientist from the 3M company laboratory. In that same laboratory, four years earlier, a glue was made that barely stuck. What a disaster! But what can not be thrown. It was too expensive and therefore they kept it. And with that poor tail the ecclesiastical scientist, Arthur Fry, was reminded, fed up with losing papers to mark in the book of the Mass. Take the tail that has been discarded, give it to paper and... to the top! It was stuck in the ecclesiastical book, but easily removed. Now, perhaps we have far enough church books, but who doesn't use those leaves?

Percy Lebaron Spencer invented that the microwave was investigating radars. In fact, it was dedicated to making magnetrons, tools that produce microwaves to make a radar. While the magnetron worked, Spencer realized that the chocolate in his pocket had melted. Therefore, microwaves had heating power. In addition, they heated the food inside, so he showed it with corn and an egg: the corn grains became popcorn and the egg burst! Subject: Microwaves are useful for heating food, but you should not try to make eggs with skin.
