Watch gas molecules that never collide with each other, only bouncing elastically off the walls of a wavy container. Change the container shape, particle count, and speed range to see how the temperature- and pressure-like readouts respond.

Legend Blue dots are gas molecules; red arrows are velocity vectors. Molecules fly in straight lines — no molecule-molecule collisions — until they bounce elastically off the wavy container wall. Average speed corresponds to temperature, and wall-collision frequency corresponds to pressure.
