They hold just about everything–Containers. We follow a day-in-the-life of a steel freight container from port to port and see how standard containers can be transported by ship, train, or truck while looking into new technology and security measures being used today. We visit a Georgia Pacific plant to see how raw materials are processed in a state-of-the-art plant. We also visit the Strategic Petroleum Reserve, an underground container used for extraordinary amounts of vital product. The containers that hold the US Strategic Petroleum Reserve are actually underground salt domes. In a visit to Bryan Mound, Texas, one of four locations housing the SPR, we learn how the caverns within the salt domes are created and how the oil contained in these caverns actually benefits from this type of storage. We also check out silos that were necessary for farmers’ progress. And finally, we sip from metal cans, which revolutionized the food and beverage industry.
