Neutral buoyancy is a condition in which a physical body's density is equal to the density of the fluid in which it is immersed. This offsets the force of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor rise.
In scuba diving, the ability to maintain neutral buoyancy through controlled breathing is an important skill.

Famous quotes containing the words neutral and/or buoyancy:
“The seashore is a sort of neutral ground, a most advantageous point from which to contemplate this world. It is even a trivial place. The waves forever rolling to the land are too far-traveled and untamable to be familiar. Creeping along the endless beach amid the sun-squall and the foam, it occurs to us that we, too, are the product of sea-slime.”
—Henry David Thoreau (1817–1862)
“She keeps
The Topic over intellectual deeps
In buoyancy afloat. They see no ghost.
With sparkling surface-eyes we ply the ball:
It is in truth a most contagious game:
Hiding the Skeleton, shall be its name.”
—George Meredith (1828–1909)
