Maple Keys
“As they fall, maple keys turn by means of their own forward motion, an effect produced by the eccentric wing, called the autogyrating principle of flight. The wing rotates around a central axis and is counterbalanced by the weight of the seed. All flying seeds have a constant center of gravity around which they revolve. This gives them stability and aids them in traveling great distances.” source

“...no one I've heard of has ever looked at a maple key and mapped out all its future branches.” source
