Buoyancy situation of fluid statics such that Archimedes principle is applicable, and is thus the sum of the buoyancy force and the object's weight If the buoyancy of an (unrestrained and unpowered) object exceeds its weight, it tends to rise. An object whose weight exceeds its buoyancy tends to sink. Calculation of the upwards force on a submerged object during its accelerating period cannot be done by the Archimedes principle alone; it is necessary to consider dynamics of an object involving buoyancy. Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle
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
