Launch Across the Floor

I nudged my dried acorn cap right up the ramp of the two wooden clothespins! Giving the little stem a quick flick with both hands, I watched it shoot off the wooden slope and glide across the dark polished floorboards! It whirled like a spinning top, skimming past the shadow of the table before settling softly against a fallen wool coaster. Dropping onto my stomach, I gathered the clothespins close, tucked the cap under my arm, and curled up right between the warm chair rungs. Our indoor racetrack is officially closed for the night, isn't it?
