This is a powder physics engine I made. Use mouse to draw. 1-5 to select material. Space to play/pause simhttps://scratch.mit.edu/mystuff/ulation. R to clear. Materials: 1. Sand can move downward diagonally 2. Water can move horizontally as well as downward 3. Stone can't move 4. Steam moves upward
Turbowarp is highly recommended: https://turbowarp.org/1352234113 Inspired by Sandboxels on neal.fun & Matbatwings' powder sim in minecraft.
