Play with the ingredients

Every explainer is a live simulation. Change the wind, the tilt, the Moon — and watch the consequences instead of reading about them.

Honest about the shortcuts

Real physics where it teaches, clearly labelled exaggerations where it must. Every explainer ships its model and its simplifications.

Everything is connected

Wind makes waves, the Moon raises tides, the seasons drive the weather. Follow the links between explainers to see how it fits together.
