Domino Path

I noticed a bunch of plastic DVD cases lined up along the lower TV shelf! I pulled five of them down one by one with a sturdy tug. They were slick and flat. I stood them on their edges in a tidy row across the striped runner rug, spacing each one just a finger apart. Once the path was set, I gave the first case a quick palm tap. Clack-clack-clack-down! They all toppled in a neat wave like flat dominoes. It made a sharp snapping sound and landed in a perfect fan shape. Setting them up again right now!
