Featured Program

After Dark: Radioactive

Warning: Certain atoms may be unstable—in fact, they’re constantly falling apart all around you. You may learn about about their occurrence in the universe, how we make use of their decay, and their effects on the human body at this evening of illuminating programming—including Full-Spectrum Science: Radioactivity with Exploratorium host and raconteur Ron Hipschman. (Don’t worry, you’ll be in no danger.)

Tactile Dome
$10; purchase tickets onsite at the Information Desk

6:15–10:00 p.m.

Take an excursion through total darkness in our Tactile Dome. Crawl, slide, and bump your way through the pitch-dark Dome using your sense of touch as your only guide through its chambers and mazes.

Please Note: Due to the nature of this experience, certain restrictions apply. Guests who are afraid of the dark; claustrophobic; have back, neck, or knee injuries; or are in their third trimester of pregnancy should not participate. Guests wearing casts are prohibited. Also, please wear comfortable clothes.
