Create exploding toilet volcanoes, oozing sink slime, and bubbling bathtub cauldrons...all in the name of science! Each step-by-step experiment uses household and other easy-to-find materials so the young scientist’s lab can be equipped quickly, inexpensively, and—for those who might worry—safely. Bathroom Science highlights the materials, the method, and the scientific "why" behind every experiment. Best of all, Bathroom Science makes science as simple (and occasionally explosive) as going to the bathroom.We’ve packed in 101 kid-challenging experiments, including... *Turn Your Toilet into a Volcano *Steam Up a Secret Message *Fill the Sink with Booger Slime *Give Bathwater an Eerie Glow *The Cackling Chicken of Death, and *Make Your Own Stink Bomb (Eew!)The folks who brought you Uncle John’s Bathroom Reader...creating the next generation of mad (and amazing) scientists, one kid at a time! (Bwa-ha-ha!)
