Celebrate July 4th with the Exploratorium's After Dark: Boom

What's the science behind fireworks? How are implosions different from explosions? What happens when hot water is combined with liquid nitrogen? The Exploratorium's After Dark: Boom celebrates July 4th with rumbling, roaring, and spectacular explorations of supernovas, sonic booms, earthquakes, taiko drumming, stepping, and other resonant topics.

Learn how the percussive powers of pyrotechnics are a time-honored and indispensible feature of every Andean fiesta at a special screening of Gustavo Vazquez's Playing with Fire (Jugando con fuego). After Dark is for adults 18 years and older. One part theater, one part cabaret, one part gallery and one part Happy Hour, After Dark is a unique way to experience one of San Francisco's most beloved museums.
