Domino Tumbler

I noticed a row of thick, colorful paperback books leaning lopsided against a brass floor lamp! They looked just like a set of heavy practice obstacles, so I dashed over and pressed my hands against the nearest spine to see how sturdy it was. With a firm shove, it tilted forward and smacked right into the next book with a loud, rhythmic thud! A whole cascade of paper tumbled down like a mini landslide, sliding across the polished floorboards. Haha, I scrambled backward just in time, hopping over a stray bookmark and landing firmly in a ready crouch amidst the fan of open pages!
