Physics Sandbox

About

Physics Sandbox is exactly what it sounds like: a falling-sand style playground where powder, liquid, lava, solids and gas all interact using real particle physics. Draw a dam and watch water find its way around it, drop lava into sand and watch it turn to glass, split solids apart and see them tumble. There's no score and no way to lose — it's the digital equivalent of poking at things to see what happens, and it's weirdly hard to put down.

Left click to draw materials, right click to erase. Drag panels to rearrange your workspace.

Tips

• Mix liquids and lava for the most interesting reactions — that's where the physics gets fun.
• Zoom out on your canvas before big builds; small ones react more predictably.
