This 1957 video by Walt Disney was produced in parallel with a book titled "Our friend, the atom." It was translated into Italian and I perfectly remember having read it when I was, maybe, ten years old. Still today, half a century later, the imagery of the book is with me. When I think of atoms, electrons are blue and protons red, as they were drawn in that book.

The clip shown here is the first of a 5-parts series. To see the whole movie, go to http://www1.teachertube.com/ and type "our friend the atom" in the search box. Clip n. 5 is especially interesting as it shows animations of what were thought to be the actual benefits that atomic energy would bring to us.
