The Brass Teeth Challenge

I hopped onto the deep armchair and found a rugged canvas backpack leaning against the cushion! Running right across the front flap was a heavy brass zipper with chunky, interlocking teeth. I clamped both hands around the cool metal pull-tab, planted my boots against the thick fabric, and hauled downward with a steady pull. Zzzzzip! The shiny teeth parted cleanly one by one with a crisp, rhythmic clatter. Prying open that stubborn metal jaw revealed a deep, shadowed pocket lined with smooth nylon. I ducked right inside and kicked my feet out, totally set for the night!
