Night Shaft Sonar

Stomped right through the heavy fire door into the stairwell canyon! Night makes the concrete hollow and cool! I spotted a tall orange plastic maintenance cone sitting beside an empty metal bucket. Zero hesitation—I shoved the inverted bucket hard against the concrete step, kicked the cone upright on top with my plush heel, and scrambled straight up! With my chin resting over the cone's hollow tip, I aimed my gaping jaws down the spiral center gap and blasted an unfiltered bellow—ZOOOOM-CLACK! The echo bounced down twelve concrete floors and buzzed all the way back up into my ribs!
