This entertaining graphic novel from award winner Dan Brown will get kids talking, since it's all about the history of dealing with poop, pee, and dirty hands.Part of the Big Ideas That Changed the World graphic novel series, this full-color book is appropriate for the classroom and includes a timeline, endnotes, and a bibliography.In 1895, an engineer named George Waring was appointed New York City’s first commissioner of street cleaning. His task? To make a city with millions of people livable.Narrated by Waring, Keep It Clean! explores the concept of public health, which means ensuring clean water and adequate sewage disposal for everyone, and covers topics such as personal hygiene, sewer systems, and chemical water treatment.Acclaimed author-illustrator Don Brown takes readers on a journey through history and around the world, from Greek, Roman, and Aztec aqueducts and the dawn of bathing (including social public bathing in Japan and religious bathing ceremonies in Machu Picchu) to the invention of soap in the Middle East, the first use of flush toilets approximately 4,000 years ago, and the first toilets used in outer space—a Big Idea when you consider that early astronauts on Apollo 11 had none!Full of facts and colorful historical figures, Brown chronicles both historical mishaps—like rivers full of human waste and King Henry VI’s notorious basement of poop—and monumental scientific breakthroughs including Louis Pasteur and Robert Koch’s discovery of the link between microbes (germs) and disease.Brown also highlights how social classes became divided not only by wealth and culture but also by smell, and calls attention to modern-day health crises.Today, nearly two billion people around the world live without clean water and about 3.6 billion people—nearly half of the world’s population—live without proper sanitation. Breaking down concepts in an accessible, kid-friendly way, this nonfiction graphic novel shows why “keeping it clean” is vitally important whether it’s a city, town, home, or person.Big Ideas That Changed the World is a graphic novel series that celebrates the hard-won succession of ideas that ultimately changed the world. Humor, drama, and art unite to tell the story of events, discoveries, and ingenuity over time that led humans to come up with a big idea and then make it come true.More from the Big Ideas That Changed the World series:Rocket to the Moon!

Awesome price for quality balls
Color: Four colors, Size: 5cm (ball only)
These balls are super bouncy and durable. My dog loves them and for the price these are totally worth it! I think they are as durable as nerf balls and equal in size, and much cheaper!

Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these. We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.
