All summer we've been pulling toys out of the box: bricks and bubbles, a yo-yo, a kaleidoscope, a lump of Play-Doh that used to be three colors. This Sunday we reach in one last time.

Dominoes. The most patient toy ever invented — all that careful setting up, one at a time, holding your breath. And then the best part, which takes about four seconds. One tap, and the motion travels farther than the hand that started it.

This is the final Sunday of Out of the (Toy) Box, and we'll be talking about the small things we set in motion and never get to see the end of. Whether you've played with every toy or you're just back from summer travels, come pull one more out of the box.
