Tension and Dampening

I pressed both hands against the rubber cap of the coiled spring doorstop fixed to the baseboard. The spiral steel resisted with firm, even elasticity. Shifting my footing on the oak plank, I pushed downward until the tip flexed forty degrees toward the floor. When I released my grip, it whipped back instantly, humming in a rapid, vibrating blur. The oscillation decayed in steady, measurable increments until the coil returned to a quiet, level rest.
