"Two years ago, the Exploratorium left from its long-time home next to the Palace of Fine Arts to occupy Pier 15 on the waterfront, a move that more than tripled their exhibition space and also put them in a building with LEED Platinum certification. The science museum features an incredible Tactile Dome, which is a maze of tunnels and slides that you go through completely in the dark using only your sense of touch—needless to say, kids love it."
