Do the Big Kid Swings REALLY make recess more fun? When there's a rule that you must be 36 inches tall to use them, Momo (who just missed it) and Puri (who just made it) ask "how can we know if the big swings actually make kids happier?" By comparing kids right at the cutoff line! Just like economists use sharp rules to uncover true effects. Playground adventures that reveal how height requirements help us measure happiness. Prepare for "aha!" moments at any age!
