Stories / The Problem of Thor Bridge
🧮 Analysis tool — freeThe Parapet Experiment
Repeat Holmes's demonstration: weight, cord, and revolver against a stone bridge.
Holmes proved the mechanism with Watson's revolver, a length of cord, and a heavy stone — fired, released, and watched the gun crack the parapet on its way into the mere. Set up the rig and see whether it clears the rail.
