Rainbow Looms and the cheap knock-offs appear to be a popular toy for elementary school children; one of my nieces has one. Today I found a 3rd grade class in which the boys were also playing with the looms to make bracelets. "Hm." Such trends come and go, though one might argue that the appeal of making such things with their own hands does not completely disappear even in Uhmerican girls. Could the boys be learning something else instead. The gender reconstructionists would object to any such redirection of boys towards more masculine pursuits.
