For every Tom Swift novel there are at least one or two inventions that just seem to be "there" as if they always existed. Or, they are important but they don't really get described as to how they came into being or how they function. This book, like the other five in this series, aim to fix that.The ten stories in this collection are individually shorter than previous novellas, but they don't need to be lengthy. These are about 6,000 words each and can easily be read in a single sitting (or reclining.) The book includes: The Big Wheel - Tom designs and builds a fast monocycleFrom Toad to Pigeon - It is time to update the Pigeon aircraft, and Tom is being asked to come up with the new designThe Little Black Bag of Medical Tools - Doc Simpson addresses the AMA and tells them about the nifty tools Tom has created for himThe Pocket Drone - A chance letter gets the inventor working on a new type of drone that can save livesThe Mechanical Arm - An employee loses an arm in an accident, and Tom is determined to replace it with the best prostheses he can buildThe Wasp - The U.S. Navy needs a tiny helicopter and Tom believes he has just the thing, assuming he can prove something never tried can work The Incredible Pen and Pencil - To Swift always has his pen radio and pencil soldering iron in his shirt pocket, but why did he make them and how?The Other Great Polymer - Tomasite is amazing but too expensive, so when Tom is building the Sky Queen he needs a new, strong polymerThe Kangaroo Kub - There is to be a midget jet carried in the Sky Queen, but can Tom design one that will land inside a moving hangar?The Repelatron - It had to come from somewhere and this is the story of how Tom came up with the very first concept, and it was years before he used it for a spaceship
