Why do some things float and others sink? An object settles with exactly the fraction ρ_object/ρ_fluid submerged — adjust the densities and watch it find its level.

floating equilibrium by density
Controls
An object floats with exactly the fraction ρ_object/ρ_fluid submerged. Denser than the fluid? It sinks. This is Archimedes' principle, live.
Reading this result: Lighter than the fluid (ρ ratio 0.60), so it floats with exactly 60% submerged — the submerged fraction equals the density ratio, and object size never changes it.

How it works
This models Archimedes' principle: the buoyant force equals the weight of displaced fluid, so an object floats with the density ratio submerged. Make it denser than the fluid and it sinks — the physics behind ships, submarines, and hot-air balloons.
