Sand & Sky

Sand & Sky is an endlessly satisfying particle physics sandbox — drop materials, watch them interact, and discover what happens when science meets creativity. Pour water and watch it fill every corner. Drop lava onto ice and forge obsidian. Ignite gunpowder and set off chain explosions. Build walls, draw mazes, and experiment unique materials that each behave according to their own rules.

REACTIONS & COMBINATIONS Every material interacts with others in surprising ways. Water meets lava and creates stone. Lightning strikes sand and fuses it into glass. Acid dissolves almost everything. Discover all the reactions in the built-in Reactions guide.

FEATURES · Realistic fluid simulation — liquids fill containers and accumulate naturally · Flip gravity in any direction — up, down, left, or right · Wind tool to push particles across the screen · Adjustable brush size and simulation speed · Undo button and sandbox clear · Unique sounds for every material

Whether you're building elaborate contraptions, running experiments, or simply watching particles fall — Sand & Sky is the perfect zen sandbox to lose yourself in.
