Rope Bridge Collapse Physics Simulation

A rope bridge simulation with real physics: wooden crates are dropped onto the bridge one after another, each heavier than the last, until the suspension bridge finally breaks. The original post is a screen recording of Opus 5.5 and Haiku 5.5 tackling the same prompt, showing at a glance how the two models differ in physics simulation. Well suited to physics explainers, model capability comparisons, or social short videos.
