The "Sink or Float" simulation is a practical way to explore the scientific principle of buoyancy, which determines whether objects float or sink in a liquid.

Buoyancy depends on the density of both the object and the liquid. Density is defined as mass per unit volume, and an object will float if its density is less than that of the liquid it is placed in; conversely, it will sink if its density is greater.

Archimedes' Principle explains that an object submerged in a fluid experiences an upward force equal to the weight of the displaced fluid. This principle is why large ships can float, while denser objects, like stones, sink.

In this simulation, spheres of different materials and various liquids help visualize how density and buoyancy lead to different outcomes, simplifying an abstract concept.
