What does density manipulation?

Density manipulation refers to the ability to alter the mass per unit volume of an object or substance, affecting its buoyancy, weight, and physical properties. This concept is often explored in scientific contexts, such as physics and chemistry, as well as in fictional narratives, where characters might possess the power to change the density of materials or their own bodies. Applications could include making objects float or sink at will, or changing the density of materials for various purposes. In essence, it involves the control of how compact or spread out matter is in a given space.
