Spencer Wright traces the evolution of the plastic bottle; why defective airbags still aren’t fixed; and how the Tylenol murders redefined packaging.

Spencer Wright, Editor-in-Chief of Scope of Work, joins Jon to uncover the hidden history of the plastic bottle, one of the most widely produced and least appreciated manufactured objects in the world. His essay, Evolution of the Plastic Bottle, published here on First Article, examines the bottle’s long evolution from early glass and acrylonitrile designs to today’s lightweight PET systems, exploring how advances in polymer chemistry, injection molding, and mass production turned an everyday object into an icon of industrial efficiency.

Jon and Alex also discuss the week’s biggest stories in manufacturing and materials—from Boeing’s completed Spirit AeroSystems acquisition to the growing strain of AI’s energy demand on the U.S. grid, and the expanding role of large-scale battery storage in stabilizing renewable energy.

The episode concludes with a Reconstruction segment on the 1982 Tylenol murders, when tampered capsules killed seven people and forced an industry-wide redesign of consumer packaging. The tragedy led to the creation of the tamper-evident seals and safety standards that are still with us today.
