How to use the bench (mouse, touch, or keyboard)
- Run it: use the buttons in the Lab bench panel (mix, heat, power on, gas tests, weigh). Play runs the bench clock (4× real time at ×1) and the particle view together.
- Zoom into the particles: the slider, the − / + buttons, scroll, pinch, or Z / X. A lens opens over the liquid; keep zooming to get closer to the atoms.
- Slow motion and steps: ×0.1 slows every particle event. Step stops after each event: press → (or Next event) for the next one.
- Look closer: point at (or tap) anything on the bench or any particle to see what it is. In a side-by-side view, tap a container to zoom into that one.
