Crazy Concoctions

Gr 3–6—Following a thorough discussion of safety, this book introduces budding scientists to a host of gross and gooey projects. A final chapter encourages them to create their own concoctions. Brown writes in an engaging, conversational style that is full of silly humor. A running gag is that Dr. Viskus Fickleschmutz was originally hired as a coauthor and, while his services were no longer needed, he somehow managed to add his thoughts (and artistic touches) to the book. In general, the experiments are familiar, such as making glop with cornstarch and water and making raisins swim using soda. Each activity has a "Stuff You Need" box; detailed, numbered steps; and a concluding "Hmmm… What's Going On?" section that explains the science behind the project. A specific icon indicates an activity that requires "an adult minion," and boxed areas are used to highlight cool facts and key individuals. Cartoon illustrations demonstrate concepts and add humor. A fun addition.—Maren Ostergard, King County Library System, Issaquah, WA
