Some of the most useful inventions were created by accident. Sticky notes are a perfect example. In 1968, a scientist was trying to make a strong glue. He ended up with a weak glue that could stick but also be easily removed. Nobody knew what to do with it at first. Then, in 1974, a man was trying to mark the pages of his song book. He used small pieces of paper, but they kept falling off. He remembered the weak glue and tried using it on the paper. The result was the sticky note—a small piece of paper that could be attached and removed easily. Another accidental invention is the microwave oven. It was discovered by Percy Spencer in 1945. He was working on radar technology and noticed that a chocolate bar in his pocket had melted. He realized that microwaves could cook food, and the microwave oven was born. These stories show that sometimes the best ideas come when we least expect them. The key is to pay attention to the unexpected and see the potential in mistakes. 1.
