A segment on the internet shows messengers running through the hallways of a large building, delivering messages in envelopes (data packets) from the user to servers and back. The hallways represent the data lines and the offices were internet hosts. In just eight minutes, the program accurately describes how the internet functions in a manner simple enough for children to understand. In the case of industrially produced things, each step is shown in great detail, so one can actually see how, for example, a piece of metal is formed by a tool. If something happens too fast for the naked eye it is shown filmed in slow motion. After each step, usually the previous steps including the new one are recapped briefly to help children remember what they already saw. Concepts which are not visible at all are explained with some form of analogous portrayal.
