The San Francisco Exploratorium squeezed between the covers of a book! The "pages" reflect, magnify, or grow as you follow the instructions. Seven subjects are covered, including light wave craziness, ouchless physics, and hair dryer science.

Finally, a long-overdue update on a classic activity. A tried-and-true play pattern is made better in this imaginative and beautiful lacing book. Each page is charmingly illustrated and the book comes packaged with the coolest lacing material on the planet (no boring shoelaces need apply).
