It’s easy for children, and all of us, to take for granted the many things we use daily: clothes, cars, homes, bicycles, and even something as simple as a pencil. The twins go on a field trip and learn that pencils are made using resources from all over the world.

They discover that people from all over the world work together in harmony to produce products that improve our lives. And miraculously, the process by which a pencil is made is the key to prosperity in our modern age—spontaneous order!
