Interactive simulators & experiments

Learn science by playing with it.

A growing collection of hands-on simulators — eclipses, orbits, rockets and whatever comes next. No installs, no sign-ups: pick one and start poking at the universe.

Why this exists

Most science is easier to understand when you can grab it and move it. Every project here is a single self-contained page that runs entirely in your browser — open it, drag the sliders, break things, and see what happens.

New simulators get added as they're built, so check back.

Adding a project

  1. Drop the project's .html file into this folder.
  2. Add an entry to projects.js (title, file, blurb, category).
  3. Set status: "live" and reload — it shows up here.
