Tom Swift's Pocket Book of Inventions

One thing all Tom Swift novels have in common is the lack of details about his lesser inventions. How did they come about? Were they part of something else of standalone projects?This series of four collections attempts to put the story behind the 'thingamy' as in, "Tom raced from the room pausing only long enough to cream the thin gamy into his jacket pocket knowing it might come in handy later on."Of course, it usually is a vital device for him, but space and word colt requirements usually meant such details had to be left out.Now you have the tales of seven of Tom's inventions, everything from the origin of his Fat Man deep diving suit to the creation of a brand new kind of forest ranger to an evacuation ball allowing injured people in his outpost in space to get back to Earth to a new jet aircraft that will become a favorite of his in the New Tom Swift Inventions Series (also available from this outlet), and a lot more.
