This chapter of Raw to Ready: Mack Truck highlights how the organic matter that has been decomposing in oceans, riverbed, and swamps for 300 million years mixes with mud and sand to create petroleum. In 1907 Dr. Leo Bakeland was looking for a new way to insulate electrical cables. His experiments with petroleum and formaldehyde lead to the discovery of a hard moldable substance he names bakelite. Bakelite is the first synthetic polymer plastic. Petroleum-based plastic is used today to make up the strong and lightweight hood of the Mack Truck.
