A cute kid’s science video! The elusive and fascinating Nature of Sound is quaintly and cleverly illuminated in this vintage film. When adorable little Jimmy becomes curious about the vibrations caused by a moving train, he goes and gets the scoop on sound from his cousin Phil Hanson. Together they explore science with a folksy charm and good nature that is largely missing from educational movies today. The Nature of Sound is an excellent physics primer on a subject that is understandable and engaging for any child.
