helping to prevent cracks or leaks by giving the plastic some flexible space to “breathe.” Structurally, it reinforces the jug’s shape, allowing it to hold its form while still using less plastic, which brings us to its sustainability perks: smarter design means less material,

and less material means a lower environmental impact. In this in-depth look, we’ll uncover the layers of thought and science packed into that simple little dent—how it works, why it matters, and how it exemplifies the subtle genius of everyday design. So go ahead—grab your cereal, pour yourself a fresh glass of milk, and join us as we explore the curious case of the milk jug dent. Spoiler: it’s way cooler than you think.
