Physics Sandbox
About Physics Sandbox
Physics Sandbox lets you experiment with a variety of materials that behave according to realistic physics simulations. You draw powders, liquids, lava, gases, and splittable solids onto a canvas and watch them interact in real time—sand pours and settles, water flows and pools, lava burns through obstacles, and gases rise and disperse. The marching squares algorithm renders everything with smooth, organic-looking visuals instead of blocky pixels, so your creations feel surprisingly lifelike. Drag materials around, combine them to see what happens, or just create chaotic chain reactions for fun. There's no objective or failure state; it's pure creative tinkering. If you've ever wanted a digital laboratory where you can pour molten lava onto a pile of sand or trap gas bubbles in water, Poki Games hosts this sandbox for exactly that kind of freeform play. Perfect for anyone who enjoys physics toys, simulation games, or just zoning out while watching particles do their thing.
