A/V Geeks 16mm Films | Free Air (1937) @avgeeks | Uploaded October 2024 | Updated October 2024, 23 hours ago.
This Jam Handy promotional film for Chevrolet explores the essential role of air in both human life and modern technology, particularly emphasizing its importance in the automobile engine. It opens by explaining that all living things need air, just as fire needs air to burn, setting up the central theme: in a car engine, a small amount of gasoline combines with a large volume of air to create power.
The film then transitions to a dramatic underwater scene where a diver struggles without proper airflow, reinforcing the necessity of air for survival. On a boat, sailors operate equipment to pump air to the diver, illustrating the importance of air in extreme environments.
The narrative shifts to everyday life examples, from a chef stoking a fire to forest firefighters, and a laboratory experiment where a candle goes out when deprived of air. These examples stress the critical relationship between air and combustion.
The film further explains how controlling the burning of gasoline is essential, especially in the modern automobile engine, where gasoline must be mixed with a massive amount of free air. Through animations and close-ups of carburetor mechanisms, the film describes how a tiny amount of gasoline (just a few tablespoons) combines with a balloon full of air to power a car.
In the climax, an experiment with a balloon and gasoline demonstrates the efficiency of the modern car engine. The balloon represents the air, and after driving a quarter of a mile, the film emphasizes how only a small amount of gasoline is consumed. The film concludes by showcasing how advancements in engineering have reduced fuel consumption, with the goal of using more "free air" and less gasoline to power vehicles.
This educational film highlights how air is not only vital for life but also for the efficiency and progress of automobile technology.

![[Citrus Fruits Can1-2, 1950s, silent]](https://i.ytimg.com/vi/hJgp69xUbgw/hqdefault.jpg "[Citrus Fruits Can1-2, 1950s, silent]
This 1950s footage showcases the intricate journey of citrus fruits, particularly oranges and grapefruits, from grove to table. The process begins with harvesting in orange groves, where farmers tend to citrus trees, planting and maintaining seedlings in dry, sandy soil. Farmers use tractors and irrigation systems to care for the groves, and the fruit is then carefully handpicked from the trees.
Once harvested, the citrus fruits are transported to processing plants, where they undergo various stages of sorting, cleaning, and packaging. Workers at the plants inspect the fruit on conveyor belts, removing underripe or spoiled ones. The oranges are washed under water sprayers, while grapefruits are cut and prepared for canning. Juice and pulp flow through machinery, and cans of citrus juice are packaged for distribution.
The footage also highlights the importance of family in citrus farming, as families tour the groves and processing plants, and gather at breakfast tables to enjoy fresh orange juice and grapefruits. The community atmosphere around citrus farming and production is evident, with a focus on both the hard work of the farmers and the joy of consuming the fresh produce. The scenes of forklifts loading boxes marked Florida Citrus emphasize the scale of production and the vital role of the citrus industry during the 1950s.
