Science Hack Day is a fantastically inspiring and creative 48-hour event where scientists, designers, artists, and developers get together to make and do science and science-related projects. You and your friends should start one! Chief instigator Ariel "Space Hack" Waldman created a guide to organize a Science Hack Day and now, she's announced the 2013 Science Hack Day Ambassador Program. Thanks to a grant from the Gordon and Betty Moore Foundation, five people who want to organize a Science Hack Day in their cities will be flown to Science Hack Day in San Francisco on September 28-29 to see how it's done. Applications are accepted until May 1.
