You've probably heard about the Texas-sized island of plastic trash swirling in the center of the Pacific Ocean. But did you know we have our own pockets of floating trash right here in San Francisco Bay? Join us on a trash safari with Sealife Convervation—a research and education group studying the volume, distribution, and sources of trash in the San Francisco and Monterey Bays.

No one puts the laws of physics to the test quite like the urban skateboarder. Join us for a closer look at the science behind the tricks of the sidewalk-shredding trade, from the basic ollie to high-flying aerial maneuvers.

Made by the Exploratorium's Teacher Institute, this "machinima"--a film made entirely in a virtual world, highlights the exhibits and recent events in Second Life on the Exploratorium Island and 'Sploland sims.

This After Dark event was devoted to the ever-mysterious and otherworldly dimensions of sleep, darkness, and night.

The original multimedia storytelling device, puppetry dates back many thousands of years and spans cultures worldwide. Join us for a back-stage look at an artistic collaboration that brings together a composer, musicians, puppeteers, and, of course, puppets to bring a story to life.

A short video created about an iconic exhibit at the Exploratorium, Ned Kahn's Chaotic Pendulum. An apparently simple set of pendulums is given an initial twist. Intuition says that the resulting motion of this simple system should be, if not simple, at least predictable. Intuition doesn't work with this device though, and its motion is an extremely complicated, and somewhat whimsical, twisting and turning that defies the predictive powers of physics.

Every night at Fort Funston, after all the people and dogs have left for the day, the bats come out to play. Dr. Gary Fellers of the U.S. Geological Survey tells us about bat vocalizations, the audio recordings he uses to monitor their travels, and the various species of bats that frequent this Golden Gate National Park.

Twenty-seven miles beyond the Golden Gate, the craggy Farallon Islands have been home to fur-seal hunters from Russia, a gold-rush-era egg business, and even a nuclear waste dump. Today they’re home to 250,000 sea birds, not to mention seals, sea lions, whales, and sharks. What makes these stark-looking islands so attractive to wildlife?

What are you afraid of? Snakes? Spiders? Heights? This After Dark event investigated the psychology and biology of fear, and included Damian Cooksey confronting his fear by demonstrating the sport of highlining far above visitors’ heads.

Tauba Auerbach talks about randomness, the unity of art and science, and the way her Geometry Playground piece uses the beauty of geometry to draw visitors into a zone of comfort with math and their own artistic capabilities.
