The Science Behind Man Surviving Underwater for Three Days
A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide stability for a vessel. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels. It also makes it easy for the crew to reduce a vessel's draft when they enter shallower water, by temporarily pumping out ballast. Airship s use ballast tanks for similar advantages. The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or argonaut octopus ,  and the concept has been invented and reinvented many times by humans to serve a variety of purposes.
