This clip from Raw to Ready: Mack Truck focuses on how organic matter decomposing in oceans, riverbeds and swamps for 300 million years, mixing with mud and sand creates petroleum. In 1907, Dr. Leo Bakeland was looking for a new way to insulate electrical cables. His experiments with petroleum and formaldehyde led to the discovery of a hard moldable substance he named bakelite. Bakelite was the first synthetic polymer plastic. Petroleum-based plastic is used today to make up the strong and lightweight hood of the Mack Truck.
