Diffusion Detective

Diffusion Detective turns invisible airborne spreading into a hands-on science investigation from a live case board: place sensor pins and sweep a sampling lens, triangulate hidden sources, shape door gaps and tape barriers, paint warm and cool air pockets that steer motion, pinch a porous curtain to separate particle sizes, time scent pulses with paired sensors, and capture equilibrium snapshots while concentration heatmaps show how random walks still drift along gradients in still air. Each mode ends in a case report built from your readings—simulated classroom evidence, not real air quality—so diffusion feels like detective work instead of a slide deck. Open Diffusion Detective and follow the trace.
