This film was part of Wonder series, made by the Moody Institute of Science, shares some similiarities with the Mr. Wizard television series - kids come by and visit the neighborhood scientist who is happy to demonstrate some science experiments.

On the surface, this 1958 film may seem like an average documentary film, but like most of films from the Moody Institute of Science, there is an ulterior motive. While revealing the complexity of nature, their films would end with Moon saying that this complexity was part of God's plan rather than evolution. Moody Institute of Science films were marketed to churches and also to public schools where today even the mention of the word "God" sparks a conflagration of protests and court cases.
