What makes soda so fizzy? And why do you wish to have antifreeze in your car? Teenager Alexa Coelho quizzed her neighbor, chemist Simon Field, with hundreds of perplexing questions, and now she has the answers. Field covers all kinds of concepts from simple to complex, but all the time with straightforward, easy-to-understand explanations. And for those readers who want to see chemistry in action, Why Is Milk White? also includes a dozen unique experiments to take a look at at home. Lift latent fingerprints from a “crime scene” the usage of super glue (for a glass or smooth surface) or iodine (for paper). Hollow out the zinc interior of a penny the usage of muriatic acid, leaving only a thin copper shell. Conduct a paper chromatography experiment to separate food coloring into its component dyes. Or use easy-to-find chemicals to create plastic “slime” Silly Putty, or a bouncing ball. This book is the perfect resource for budding scientists in every single place.
