Tonight's Schedule of Events
Full-Spectrum Science
With Ron Hipschman
8:00 p.m. | Osher Gallery 1, Kanbar Forum
Join Exploratorium scientist Ron Hipschman for colorful explorations of the physical world. Are the primary colors really red, yellow, and blue? How can you get yellow from mixing red and green together? Bring your most colorful questions to this vivid presentation.
Kaleidoscope
By Karina Smigla-Bobinski
6:00–10:00 p.m. | Osher Gallery 1, Black Box
Experience a landscape of astonishing visual effects. Constructed as an 8-foot-square light table, artist Karina Smigla-Bobinski’s Kaleidoscope invites you to manipulate layers of inks comprised entirely of the primary colors. Each touch of the surface generates hyperdynamic images that visualize motion energy.
Curious Contraptions
6:00–10:00 | Gallery 2
Explore fantastical, often amusing mechanical sculptures known as automata. These small, handmade flying, sailing, and cycling machines bring whimsical dramas to life through low-tech mechanisms, inviting you to investigate how they work.
Glow
6:00–10:00 p.m. | Bechtel Gallery 3
Celebrate the holidays and excite your atoms at Glow, our annual festival of ebullient lights and subtle glows celebrating the close of the year.
Tactile Dome
$106:15–10:00 p.m.
Osher Gallery 1
Journey through total darkness in this twisting, turning, tactile sculpture. Walk, crawl, climb, and slide your way through a wonderland of textures using only your sense of touch as a guide.
