What changed.

Publication dates belong to the articles. A new software deployment does not make an old story new.

  • How a zipper works

    Redrew the selected states so the slider position and joined length change together; separated guiding, holding and slider locking.

  • How a siphon works

    Added comparisons for a lower outlet, equal endpoint heights and an interrupted liquid path; clarified priming as a starting condition.

  • How a drinks can tab works

    Added separate initial-venting and panel-opening lever states, with explicit changing contact points and retained hinge.

· Reading routes

Three ways to follow an idea.

Added reading trails on pressure and flow, holding and releasing, and material structure. Each route explains why its stories connect and where the comparison stops.
