Free for After Dark Members
Adults Only (18+)
Note: The Tactile Dome and some programs have limited capacity and are available to visitors on a first-come, first-served basis.
Lose yourself in over 650 interactive exhibits exploring perception, art, and science at our adults-only After Dark. Grab your friends and a drink and get immersed in mind-bending experiences and unique, thought-provoking programs.
Data shows that our climate is changing. Find out how scientists know what they know, learn how to dive into the data for yourself, and consider three artists' responses to our shifting environment.
It’s All About the Data
With Ron Hipschman
7:00 p.m. | Kanbar Forum
The Exploratorium’s site at Piers 15 and 17 isn’t just a museum campus—it’s also a giant environmental data collector gathering data for use by teachers, students, the public, and the Exploratorium’s own scientists. These sensors monitor the environment long-term to measure both the weather (what it’s like outside now) and the climate (how the weather is changing over time). See the sensors, learn what’s being measured, and learn how to access the data yourself.
Welcome to Your Warming World
With Lori Lambertson
9:00 p.m. | Kanbar Forum
Go beyond the headlines and get to know the data on climate change. Higher carbon dioxide concentrations in the atmosphere are correlated with warmer air temperatures, sea-level rise, ocean acidification, smokier skies, and more extreme weather. Come examine the data and the possibilities of the “new normal.”
Awareness and Action: Exploratorium Artists Respond to Climate Change
With Rosten Woo, Sara Dean, and Byron Au Yong
8:00 p.m. | Fisher Bay Observatory Gallery 6
As our climate changes, will we change, too? Artists Byron Au Yong, Sara Dean, and Rosten Woo discuss art and design as tools—for communicating about climate change, inspiring civic agency, and building resiliency into physical, intellectual, and emotional spaces.
The Wired Pier
6:00–10:00 p.m. | Osher Gallery 1
The Wired Pier is an array of sensitive instruments around the Exploratorium campus at Piers 15 and 17, measuring and recording conditions in the environment—the weather, Bay water, pollution, and more. Live data appears on the Wired Pier website and in the Fisher Bay Observatory Gallery 6, and is archived so that the Exploratorium’s scientific partners and the public can explore patterns and trends in the atmosphere, oceans, and urban landscape.
Earth Video: Selections from the Exploratorium
6:00–10:00 p.m. | Bechtel Gallery 3, Webcast Studio
From the bottom of the ocean to the tops of tall mountains, the Exploratorium has investigated the sites and systems of planet Earth (and beyond!) over the past fifty years—and taken plenty of video. Get glimpses of our dynamic environment, including the inner and outer workings of water, climate, salt pond restoration, the Bay, biofuels, and more, from the deep resource that is the Exploratorium archive of environmental film.
With Chirp Chips
6:30–9:30 | Bechtel Gallery 3
There are over 2,000 types of edible insects in the world, which tend to be packed with protein and easier on the environment than raising meat for billions of humans to eat. In fact, more people on Earth already consume insects than speak the English language. Taste a variety of insects in a variety of forms, including Chirps—corn chips made partially with the faint nuttiness and extreme environmental friendliness of cricket flour.
6:00–9:45 unless noted
Various locations throughout the museum
Ticketing at 6:00 p.m., first come, first served
Osher Gallery 1
Draw hypnotically flowing patterns with a swinging table, and watch friction cause the patterns to slowly shrink along a spiral path. Pick up a ticket to reserve your spot in line for this popular activity.
Bechtel Gallery 3
Tune in to surrounding sounds by experimenting with strings and vibrations, and use electromagnets to build a basic speaker. Learn how to listen with your bones, and explore the workings of the inner ear.
Cow Eye or Flower Dissection (alternating)
Do cows see color? How does a lens work? Examine the intricate structure of a cow eye to learn about similar structures in our own eyes, as well as some key differences.
Stigma, stamen, pistil, anther, style: Uncover the beautiful architecture of flower anatomy, and gather some surprising strategies that plants use to reproduce.
Osher Gallery 1
Everything is not as it seems—at first. Pick a card, any card, and watch the Explainers reveal some surprising aspects of human perception.
