Neutral buoyancy means you neither sink nor float. You're as dense as the water around you so you just kind of hang there suspended at whatever depth you want to be. NASA use it to simulate zero gravity.

Neutral buoyancy means that an object can be fully submerged in a fluid (usually water), and neither float nor sink. The force of buoyancy (the fluid pushing up on the object) and the force of gravity on the object both add up to zero.
Had the object been placed there very steadily, it would remain in place. If it were to be disturbed to either go up or down, it would drift all the way up, or drift all the way down (at constant velocity, unless drag is significant).

Neutral buoyancy is a condition in which a physical body's mass equals the mass it displaces in a surrounding medium (water). 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.
