Interactive science comedy showcase Eureka! demystifies science through laughter. Twice a month, San Francisco's PianoFight hosts guest scientists to give a talk on a grab bag of brainiac topics. Meanwhile, comedians riff and banter with them, producing a hilarious experience ... that may even be educational. Plus, you can get in on the action by answering the expert's questions in exchange for fun, theme-related prizes.
