Everything Matters: Technetium
With Ron Hipschman
8:00 p.m. | Osher Gallery 1, Kanbar Forum
The element technetium was known to science long before it was discovered, and when it finally came to light, it was the first primarily synthetic element to be produced in a lab. Get the details on the race to find this “missing” element and how a Bay Area scientist helped get the job done at Everything Matters: Technetium with Exploratorium scientist Ron Hipschman.
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.
6:15–10:00 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.
