Great museum located on the piers line of San Francisco. It has lots of activities for kids and big enough size to fit all the people going into.
There are number of experiments with liquids, electricity, light, and all of them have quite clear description nearby. It say what's happening and why in short and easy to understand posts.
There is a parking lot right across the street. When you pay for it, mention that you are going to go into the Exploratorium, and you will get more than 50% off the cost.
