To feel the musing, listen to LOUD Music,
Resound with your deafening colours,
A firework ricochets off your sounds,
Flood your soul, splash all your walls,
Bathe your eyes and suffuse your ears,
Skim your poetries to bounce your wild ideas,
Let the light strikes your sensitive cord,
To feel the musing, listen to LOUD music.

When conditions are just right, the low pressure at the center of a wingtip vortex can drop the local temperature below the dew point, causing condensation to form. Here vortices are visible extending from the tips of the propellers in addition to the wingtip. Because of the spinning of the propeller and the forward motion of the airplane, the prop vortices extend backwards in a twisted spiral that will quickly break down into turbulence. The same behavior can be observed with helicopter blades. (Photo credit: benurs)
