A vapor cone (also known as a Mach diamond, [1] shock collar, or shock egg) is a visible cloud of condensed water that can sometimes form around an object moving at high speed through moist air, such as an aircraft flying at transonic speeds. When the localized air pressure around the object drops, so does the air temperature.
Cernan's suit was tested using the Spacecraft 9 life support system after the flight, when it was discovered that a small patch of the visor treated with an anti-fog solution remained clear of condensation. Later Gemini flights all included the anti-fog solution, for application prior to the space walk occurring.
The water-vapor condensation mechanism in wingtip vortices is thus driven by local changes in air pressure and temperature. This is to be contrasted to what happens in another well-known case of water condensation related to airplanes: the contrails from airplane engine exhausts.
Surprising Use: Oiling and draining water. Standard padlocks are built with one to two tiny holes in the bottom surrounding the keyhole. Since padlocks are often used outdoors, the main purpose of ...

Condensation forming in the low pressure zone above the wing of an aircraft due to adiabatic expansion. Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. [1]
Condensation in the atmosphere forms cloud droplets. Also, a net condensation of water vapor occurs on surfaces when the temperature of the surface is at or below the dew point temperature of the atmosphere. Deposition is a phase transition separate from condensation which leads to the direct formation of ice from water vapor.
Rain-X is a synthetic hydrophobic surface-applied product that causes water to bead up and run off surfaces, most commonly used on glass automobile surfaces. The brand has since been extended to a range of automotive and surface care products, including wiper blades.
