physics sandbox

Physics Sandbox Build, float, sink, swing and launch: a sandbox where every part follows real physics. SPAWN Pick a block, sphere, cylinder or wedge and set its density. Below 0.5 it floats, above 0.5 it sinks, and at exactly 0.5 it hovers. EDIT Change a part's density, scale or color, anchor it in place, reset its speed, or delete it. Drag the red, green and blue arrows to move a part along any axis. ROPES Tie your parts together with physical ropes that swing and collide. You can also rope your parts to your friends' parts and build something together. FORCE Choose a direction, set a force in kN and how long it lasts, then hit Push! Heavy parts barely move, light ones fly. Weight, gravity and air drag decide what happens next. Your parts belong to you. Only you can move, edit or delete them, and they're cleaned up when you leave. Experiment, build machines, and see how far you can launch things!
