The Locker Loop

Plink! A tall green metal locker door, cold and slick. Prime climbing ground! I reached out. Smack! Both hand cups sealed tight against the glossy enamel. My feet swung out into the hallway air. Whoosh! Instead of dropping, I whipped my legs backward into a full reverse loop. Snap! My right foot clamped onto the thin rim of a horizontal vent slit above. Suspended upside down! Right then, the loud school bell buzz rattled through the steel door. Did I shake loose? Not a chance! My rubber spine flexed, swallowed the shock wave, and sprung right back taut. Still anchored. Zero slip!
