What Is the Magic of Wistling?

A oswald writes, occasionally, parents or other adults inadvertently encourage magical behavior in their children. For example, nurses have been known to employ whistles to ote make the child urinate. And kindly grandparents not infrequently whistle away the aches and bruises of a youngster. But he ends up talking about whistling as a form of non verbal signalling. He describes some of the same research we have already talked about, for example, that whistling is a type of noise making that travels especially well by concentrating energy in the one to four killaherts range. It's sort of a perfect attention gitter.
