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:
“I feel the carousel starting slowly
And going faster and faster: desk, papers, books,
Photographs of friends, the window and the trees
Merging in one neutral band that surrounds
Me on all sides, everywhere I look.”
—John Ashbery (b. 1927)
“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)
