The Bobbing Spring

I noticed a tiny coiled wire... sitting upright near the corner of the low audio shelf. It was a shiny metal spring from a click pen, standing like a little silvery tower. I paused... holding my breath, and crept forward one quiet paw at a time. When I leaned in close, I tapped the very tip with my front paw. Boing! It compressed down, then leaped straight up into the air with a faint, musical ping, tumbling onto a nearby felt coaster. I curled low behind the shelf leg, watching it wobble until it was still.
