Film on the use of farm products in industry and the growing of crops that we now import such as the vetches, sugar beet seed, clover, etc. The utilization of farm crop covers such crops as soy beans, peanuts, wood, flax, milk and a number of other products of which we normally have a surplus
"The basic chemical similarities between the coal and oil groups and the grains is clearly explained. Then it is shown how, because of these chemical bases, grasses and coal or oil may be transformed into substitute materials. Clothing materials are also analyzed, so that rayon and other synthetic products are explained. Excellent for all biology, general science, and beginning chemistry groups." Collaborator

"This color film tells of the activities of the du Pont Company in bringing to our everyday life new and useful products made possible through chemical research. The film opens with views of laboratory apparatus as the narrator states that the chemical laboratory is in the vanguard of modern progress.
"First, a realization of chemists' dreams is shown in Neoprene. . . Next, liquid-repellent fabrics are demonstrated in a dramatized skit. Fire-retarding agents, useful for women's dresses, are demonstrated.
"To make rayon, cellulose sheets are shredded, liquefied, and forced through spinnerets, wound on spools, dyed, and woven. A West Virginia plant which makes Nylon is next shown, with a brief explanation of raw materials and some of the methods. In a hosiery mill, the Nylon thread is knitted into women's stockings. Other uses of this 'product are shown in the making of brushes and fishing line. The Lucite plastic ... is demonstrated. We also see furniture and other household articles made of this and other plastics. The flLn ends with scenes of girl models in their synthetic dress and using synthetic furniture. as the commentator emphasizes the value of chemistry to our life.
"An excellent film for use in chemistry and physics classes; should have some value for social science classes, and should be very effective in general showings, at the junior high level and above. Of limited value also in elementary grades. The film makes effective use of color; photography and sound are good. . . In a few scenes models appear clothed in undergarments and bathing suits; some schools may consider these scenes unsuitable for their showings. For that reason, it is recommended that the film be screened by faculty members before being exhibited to students." Educational screen
