A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation.
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space structures employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, billowing, and suction.

Newton's Apple is an American educational television program produced and developed by KTCA of Minneapolis–Saint Paul, and distributed to PBS stations in the United States that ran from October 15, 1983, to January 3, 1998, with reruns continuing until October 31, 1999. The show's title is based on the legend of Isaac Newton sitting under a tree and an apple falling near him—more popularly, on his head—prompting him to ponder what makes things fall, leading to the development of his theory of gravitation. The show was produced by Twin Cities Public Television (TPT). For most of the run, the show's theme song was Ruckzuck by Kraftwerk, later remixed by Absolute Music. Earlier and later episodes of the show featured an original song [ Was it original? It was certainly the identical music from Suburb's Music For Boys, a Minneapolis new wave band ]
Inflatable castles are temporary inflatable structures and buildings and similar items that are rented for functions, school and church festivals and village fetes and used for recreational purposes, particularly for children. The growth in the use of such devices has led to a rental industry that includes inflatable slides, obstacle courses, and games. Inflatables are ideal for portable amusements because they are easy to transport and store.

Certain species of fish and birds are able to locomote in both air and water, two fluid media with very different properties. A fluid is a particular phase of matter that deforms under shear stresses and includes any type of liquid or gas. Because fluids are easily deformable and move in response to applied forces, efficiently locomoting in a fluid medium presents unique challenges. Specific morphological characteristics are therefore required in animal species that primarily depend on fluidic locomotion. Because the properties of air and water are so different, swimming and flying have very disparate morphological requirements. As a result, despite the large diversity of animals that are capable of flight or swimming, only a limited number of these species have mastered the ability to both fly and swim. These species demonstrate distinct morphological and behavioral tradeoffs associated with transitioning from air to water and water to air.

Fins are usually the most distinctive anatomical features of a fish. They are composed of bony spines or rays protruding from the body with skin covering them and joining them together, either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim.
