physicslabs

Twelve interactive physics labs for kids aged 8 to 12, built with Three.js and made for phones.

The solar system experiment: planets on their orbits against a dark sky, with sliders and buttons below. — The solar system experiment, with sliders for time speed and the Sun's mass.

There are twelve labs: the solar system, a star's life, a black hole, the double slit, the atom, tunnelling, the Milky Way, a galaxy collision, the expanding universe, a prism and rainbow, lenses and mirrors, and why the sky is blue.

In the double-slit lab you fire electrons one at a time and watch the stripes build up. In the solar system you can make the Sun heavier and see the planets fall in or fly off. Each lab runs a real model and says where it simplifies. The solar system starts from NASA JPL positions for 1 January 2026, and the tunnelling lab solves the Schrödinger equation in one dimension.

Built with Three.js and Vite.
