Whirlybird Test Flight

I scooped up a dried maple seed resting against the weathered slats of a park bench. Its papery, asymmetric wing immediately reminded me of a miniature rotor blade. Curious about how nature handles pitch and lift, I scrambled up to the very top rail of the backrest, raised the seed high above my head, and gave it a gentle flick. The moment it caught the downward air, it snapped into a rapid, fluttering spin, drifting lazily in a wide spiral before softly settling onto the gravel path below. Watching natural autorotation work on the exact same aerodynamic principles as my own twin tails was pure delight.
