PG is getting on in years, and he bought a brilliant, cherrywood cane to help him walk. PG named the cane Harvy, and the two became great companions. The special thing about Harvy is that he can talk. He has the inquisitive mind and vivid imagination of a child and a special curiosity about science. The story begins at JFK airport where Harvy is entranced by escalators, and he wonders where the moving stairs go once the basement fills up. Harvy also wonders about the origins of this mystical force called gravity. He's fascinated by the laws of buoyancy, flotation, and the wonders of flight. Why don't airplanes have to flap their wings like birds fly? Why can humming birds hover without having rotating blades like a helicopter?
