Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.

Why can a submarine sink and float in sea water?
A submarine has "ballast tanks" which can be filled with water to make the vessel heavier (total density greater) than water and dive to required depth. These ballast tanks can also be filled with air (compressed air is kept on board for this) to make the vessel lighter and rise to the surface

Where can you purchase ballast tanks?
Ballast tanks aren't necessarily a specific item - they're designed specifically for the vessel involved, and custom built. Main Ballast Tanks are nothing more than open air spaces between the outer hull and inner hull of a submarine; they're normally full of air on the surface, and a hydraulically actuated valve (which can be manually operated as well if needed) opens to release the air through a vent at the top of the tank, letting water in through open grates in the bottom of the space. Variable Ballast Tanks (Trim Ballast Tanks) are simply water tanks of custom design and manufacture for each individual boat. They're tied to pumps that can rapidly fill or drain each tank as needed for increasing ballast, or leveling the boat. Anything that holds water and can be connected to a pump which can fill and drain it can be used as a ballast tank.

How many ballast tanks are there in a submarine?

If a sumbarine submerges what is it doing?
A submarine is a sea going vessel that is designed to run submerged or on the surface of the sea. Basically, by filling ballast tanks with sea water, the submarine will sink, and by blowing out the sea water from the ballast tanks with compressed air, the submarine will float on the surface.
