Helicopter Trajectory Test

I spotted three dried, double-winged maple seeds resting on the curb—what if their aerodynamic balance is completely compromised?! What if a rogue updraft sends them spinning in chaotic, unrecoverable loops?! I couldn't just leave them untested. Scrambling onto the flat top of a brick border, I hoisted the largest seed pod with both hands. My fingers were trembling—what if it simply drops like a stone?! I leaned over the edge, held my breath, and let go. It didn't drop! The stiff brown wing caught the breeze instantly, whirling in a dazzling blur of mini-propeller spins before settling softly onto the moss below. I clasped my cheeks—pure, self-stabilizing physics!
