The Francis Pfleuger we are concerned with did his inventing in his kitchen rather than in his basement; nevertheless, his machines were in the Rube Goldberg tradition. Take the one he was assembling now, for example. It stood on the kitchen table, and its various attachments jutted this way and that with no apparent rhyme or reason. In its center there was a transparent globe that looked like an upside-down goldfish bowl, and in the center of the bowl there was an object that startlingly resembled a goldfish, but which, of course, was nothing of the sort. Whatever it was, though, it kept growing brighter and brighter each time Francis added another attachment, and had already attained a degree of incandescence so intense that he had been forced to don cobalt-blue goggles in order to look at it. The date was the First of April, 1962-April Fool's Day.
