Buoyancy "downward" direction. The center of buoyancy of an object is the centroid of the displaced volume of fluid. Archimedes' principle is named after Archimedes of Syracuse, who first discovered this law in 212 B.C. For objects, floating and sunken, and in gases as well as liquids (i.e. a fluid), Archimedes' principle may be stated thus in terms of forces: — with the clarifications that for a sunken object the volume of displaced fluid is the volume of the object, and for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.

Bath salts soap, even though the soap is coming off faster, because the soap remains soluble. High concentrations of salts increase the density of the water and increase buoyancy, which makes the body feel lighter in the bath. Very high concentrations of salts in water are used in many isolation tank therapies. Isolation tanks are special baths with enclosures which block out all light. Researchers have also studied their use in treating arthritis. Bath fizzies are material products designed to effervesce in bathwater. They come in the form of amorphous grains of homogeneous mixture, packaged in a box, jar, or envelope; single-use
