Neutral buoyancy
From Wikipedia, the free encyclopedia
Neutral buoyancy is a condition in which a physical body's mass equals the mass it displaces in a surrounding medium. This negates the effect of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor float. Instead it will remain at its current level in the medium that surrounds it.
In scuba diving, the ability to maintain neutral bouyancy through controlled breathing is an important skill.
