Creating Neutral Buoyancy
Creating neutral buoyancy is simple. Find an object, and two fluids, one that is more dense and one that is less dense. In the first fluid, the object will float. In the second, it will sink. However, when you mix the two liquids, it will be somewhere in between, because the force of gravity pushing down on the object equals the force of buoyancy on the relative density of the object, causing it to land in the middle of the fluid. There are exceptions to this rule however, as is the case with insoluble liquids. Because they do not mix well, one stays suspended on top of the other, and any object dropped onto the liquid will land according to its density.

Famous quotes containing the words creating, neutral and/or buoyancy:
“Whoever undertakes to create soon finds himself engaged in creating himself. Self-transformation and the transformation of others have constituted the radical interest of our century, whether in painting, psychiatry, or political action.”
—Harold Rosenberg (1906–1978)
“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)
“The boatmen appeared to lead an easy and contented life, and we thought that we should prefer their employment ourselves to many professions which are much more sought after. They suggested how few circumstances are necessary to the well-being and serenity of man, how indifferent all employments are, and that any may seem noble and poetic to the eyes of men, if pursued with sufficient buoyancy and freedom.”
—Henry David Thoreau (1817–1862)
