Thank you, Cy . . . for opening up the world of tinkering and creativity to a whole new generation . . . looking to get their hands dirty with new and exciting projects. —NPR's Ira Flatow, host of Science Friday

Cy Tymony's The Sneaky Book for Girls picks up where The Daring Book for Girls left off. While The Daring Book for Girls includes pointers on secret note-passing skills, The Sneaky Book for Girls goes one step further by showing gals how to write a note in invisible ink, craft the note into a sneaky Frisbee, and then properly recycle the note after its secrets have been divulged.

In addition to profiles of more than a dozen famous women, this clever book also provides complete how-to instructions, along with diagrams for sneaky gadgets, survival skills, magic tricks, communication codes, science and crafting projects, as well as recycling and conservation techniques.
