Feather

Feather: Easy to understand

Imagine trying to stay warm on a chilly day while also needing to move quickly to catch a bus. This is similar to how a feather functions on a bird's skin, where it provides both insulation and the lift necessary for flight. Just as a good jacket keeps you warm and allows flexibility for movement, feathers insulate birds from the cold and provide the aerodynamic properties needed for flight.
