Cities are known to produce a lot of light pollution, making it a challenge for astronomy enthusiasts to view the heavens within city limits. For us in the SF Bay Area, these issues apply, however, exciting results can still be attained between sky gazing and learning about how we all fit into this big thing we call "space". Urban Astronomer Paul Salazar, The Exploratorium's very own Adam Esposito and more demonstrate how to deal with the parameters and the unforgettable experiences that await with simple to no equipment, the right conditions, and some decent timing.

The World's First Book Printed with Conductive Ink! The Art of Tinkering is an unprecedented celebration of what it means to tinker: to take things apart, explore tools and materials, and build wondrous, wild art that's part science and part technology. Its cover is printed with a special ink that conducts electricity, allowing readers to make their own circuits right on the book and get in on all the tinkering fun. The wonder continues inside the book, where readers meet 150+ makers and learn the stories behind their beautiful and bold work.
