Almost everything around you, from paper clips to computers, was thought of, designed, and built by humans. An invention can be a totally new idea, or an improved variation on something that already exists. Inventors invent to solve problems and make life easier. Anyone can be an inventor, even you. All you need is an idea, and sometimes you don’t even need that. Silly Putty, sticky notes, X-rays, pretzels and nylon were all accidents that became great inventions after more research, experimentation, and design.
