With triple the space at its new Pier 15 location, the Exploratorium promises to build on what was already a must-see San Francisco experience.
The new building opens to the public April 17 and adds 150 brand new exhibits -- including a free outdoor space -- to the experience.
"It was a bit dark," Dennis Bartels, the center's executive director, said of the old space where the hands-on museum lived for 43 years in the Palace of Fine Arts.
He said the new center with views to both the city and the bay will be more accessible.
Some 200 journalists attended the preview Tuesday.
Advanced tickets are for sale online. Tickets are $25, with discounts for various groups. For more information visit www.exploratorium.edu. Read the full preview in the April 19 ticket section.
