this book has many short stories, 114 to be exact, that explain how some things were invented. They tell who invented it, how they invented it, when and where they invented it. It talked about aspirin, ball-point pen, a balloon, a band-aid, bikini, blue jeans, cereal, calculator, straw, doughnut, cologne, gum, comics, dice, ice-cream, sundae, pockets, pencils, wigs and many other inventions of everyday life. I though this book was a great book because it talked about inventions that I haven't really thought as inventions. It's a book with simple facts of the things we use.
