  2. Cartesian diver - Wikipedia

    en.wikipedia.org/wiki/Cartesian_diver

    A Cartesian diver or Cartesian devil is a classic science experiment which demonstrates the principle of buoyancy (Archimedes' principle) and the ideal gas law.The first written description of this device is provided by Raffaello Magiotti, in his book Renitenza certissima dell'acqua alla compressione (Very firm resistance of water to compression) published in 1648.

  3. Ocean surface ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ocean_surface_ecosystem

    Most prominently, the surface is home to a unique community of free-living organisms, termed neuston (from the Greek word υεω, which means both to swim and to float). Floating organisms are also sometimes referred to as pleuston, though neuston is more commonly used. Despite the diversity and importance of the ocean's surface in connecting ...

  4. Ocean-bottom seismometer - Wikipedia

    en.wikipedia.org/wiki/Ocean-bottom_seismometer

    The two sphere halves are put together with an O-ring and a metal clamp to hold the halves together. A slight vacuum is placed on the sphere to better ensure a seal. The sphere by itself floats, so an anchor is needed to sink the instrument to the bottom. In this case, the anchor is a flat metal plate 40 inches (1.02 meters) in diameter.

  5. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle can be applied alone. For a floating object, only the submerged volume displaces water. For a sunken object, the entire volume displaces water, and there will be an additional force of reaction from the solid floor.

  6. Neutral buoyancy - Wikipedia

    en.wikipedia.org/wiki/Neutral_buoyancy

    Neutral buoyancy occurs when an object's average density is equal to the density of the fluid in which it is immersed, resulting in the buoyant force balancing the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it is less).

  8. Buoyancy - Wikipedia

    en.wikipedia.org/wiki/Buoyancy

    Buoyancy (/ ˈ b ɔɪ ən s i, ˈ b uː j ən s i /), [1] [2] or upthrust is a net upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

  9. Cheerios effect - Wikipedia

    en.wikipedia.org/wiki/Cheerios_effect

    The effect is observed in small objects which are supported by the surface of a liquid. There are two types of such objects: objects which are sufficiently buoyant that they will always float on the surface (for example, Cheerios in milk), and objects which are heavy enough to sink when immersed, but not so heavy as to overcome the surface tension of the liquid (for example, steel pins on water).
