Changes

A Human Powered Submarine (HPS) is commonly used as a technical defiition for the act of a human wearing specialized shoes (Herein referred to as "Flippers") designed to have the effect of extending and streamlining the feet, thereby maipulating the scalar magnitude of their resistance in the water. The operator (Human) will therein manipulate itself in such a fashion as to affect ascension and declination through water. Inconveniently, A Human Powered Submarine is vulnerable to changes in atmosphere, and when operating a human powered submarine, specifically during descent, it is recommended that evasive maneuvers are initiated until a time at which equilibrium is restored.
