Technology on Instagram: "Before water and soda bottles reach their familiar form, they start out as small plastic pieces called preforms. These preforms, which resemble thick test tubes, are made from durable PET plastic. During manufacturing, they are heated until soft and flexible, then placed into a bottle-shaped mold. A burst of high-pressure air expands the preform to fill the mold, giving it the exact shape of a bottle. After cooling and hardening, the mold opens to reveal a finished bott

Explaining How It’s Actually Made on Instagram: "First, heated plastic preforms are pressed inside precision molds, shaping the rounded bases that will later form the foundation of each bottle. Consistent pressure and temperature ensure identical curves, creating a stable structure ready for stretching and refining. This early stage sets the standard for the bottle’s final durability and uniformity. Next, the semi-formed pieces are transferred for blowing, where high-pressure air expands them in
