Cable Tunnel Inspection
I rolled my coiled zip tie across the floor until I bumped right into a tangled cluster of thick black television cables! They arched like a grand underground suspension bridge. I tried pushing my zip wheel through the gap, but the opening was just a pinch too narrow. No problem! I stepped down, hooked two fingers around a rubbery cord, and nudged it upward with my shoulder until it settled into a neat, stable arch. Then I gave my plastic ring a solid shove, and whoosh—it zipped straight through the tunnel to the other side!
