Every Halloween I try a lesson on science and superstition. This week's was Orson Welles radio version of "War of the Worlds" and the hysteria it made. Listen to it, there are pauses, places you can here "do you here that?" Students moved forward and gestured that they could not hear. Supposedly, a bunch of good ole boys shot up a neighbor's water tower thinking it was a Mars Walker. I asked the students if they knew anybody who would do that. Not only were there hands, there was pointing to specific students.
