Celebrate July 4th with the Exploratorium’s After Dark: BoomPost an Event »

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 indispensable 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. Tickets are $15; $10 for members. 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.
