This is a pixel-based physics sandbox — drop sand, water, and fire and watch them interact in real time. Sand piles up, water flows and fills gaps, fire spreads and burns. Draw walls, mix elements, and see what chaos you can cook up. Works on mobile and desktop. This is a work in progress, so expect some bugs. I'll try to fix them and potentially add new features when I have the time and energy. Notes and Credits: Inspired by the Sand:Box app available on Google Play. Changelog: July 16, 2026 - Initial beta release July 17, 2026 - Added ash, fixed some heat capacity values, fixed the brush size slider July 20, 2026 - Improved speed, consolidated and added settings to a dedicated settings menu #physics #sandbox #simulation #pixelphysics #fallingsand #sand #water #fire #particles #elements #game #interactive #simulator
