If you ever want to see what it is like to be like Helen Keller, put on earplugs and descend into the darkness of the Tactile Dome. But, make sure you call a day ahead and schedule an appointment first.
This place is for all ages, even 3 year olds enjoy playing with the hands-on experiments. They just don't know they are learning.
Free admission via reciprocal membership through ASTC. There is a toddler area so that they are not completely left out. Allot a day for this activity. They are located in the Marina district and close at 5pm. ( http://www.exploratorium.edu )
