Physics simulation you can play with right now

Hundreds of physics simulation projects, each running live on its creator's own site: some of them vibe-coded with AI, all of them playable in your browser with nothing to install. Press a card to play one on its own page, or start the cruise to ride through them one after another.

Worlds that obey rules: falling sand and lava, cloth you can drag and cut, jelly you can slice, black holes bending light, fluids that swirl where you stir them. Poke everything, because most of these are built to be pushed around.

Questions about physics simulation

What is a physics simulation?

Code that steps a model of the real world forward many times a second: gravity, collisions, springs, fluid flow. Each frame it works out the forces, moves everything a little, and draws the result.

How do I interact with one?

Click, drag and throw things with the mouse or your finger. Many have a control panel for gravity, wind or materials, and a reset button for when you have broken everything.

Is this real physics?

Real enough to feel right. Most use simplified methods tuned to run live in a browser, like position-based dynamics for cloth and soft bodies, while a few are teaching labs that try to match the textbook.
