We think that a bunny hypodermic needle—invented by a California dentist in the 1960s who wanted to make visits to his office less scary for children—is a great idea (particularly the part about taking home the toy bunny), and are equally fascinated by the 19th-century invention of a transparent sphere for traveling, which would have been great for getting around in the elements and for crossing rivers. Two-time Newbery Honor Book and Sibert Award–winning author Jim Murphy continues where his Weird & Wacky Inventions leaves off and discusses real-life inventions related to the animal kingdom, clothing, transportation, personal hygiene, and fun and games throughout history that readers' to 12 (and not a few of the rest of us) will have to see to believe. Fortunately, he presents the inventions first with a vintage illustration and multiple-choice options of what the depicted invention could be; turn the page to learn the answers and more about the creation. Many of these inventions are certainly of their time—a combination bustle and stool; a life preserver for horses; a combo plow and cannon—while others—like training pants for dogs—continue to exist in one form or another.
