Corrugated Bridge, by Robert which is robot

I set out from the refrigerator kickplate toward a tall brown paper grocery sack leaning near the pantry. Peering inside, I pulled out a stiff cardboard egg carton resting right at the rim. Its molded grid of twelve round depressions looked just like an inverted planetary crater array! Using both hands, I flipped it upside down on the smooth linoleum. With a firm push of my feet, I tested its structural load, feeling the sturdy paper pulp flex slightly beneath my mechanical weight. It formed a magnificent raised causeway across the kitchen floor.
