The aim was to take the San Francisco Exploratorium (the granddaddy of all hands-on science museums) and squeeze it between the covers of a book. Inside the book are “pages” that reflect, magnify or grow into ugly bacteria-infested messes if you spit into them (per the instructions). Seven subjects are covered, including light wave craziness, ouchless physics and hair dryer science. More than 50 activities, plus the tools to do nearly all of them. All you supply is the world around you, and a little curiosity about what makes it tick. Includes a light-ray defractor, heavy duty magnet, agar gel and much more. Certain to amuse and teach! Heavy-duty spiral binding will hold up to use.
