Checked out the Exploratorium for their free day. It was so much fun, so many activities to do and ways to learn. Although it was quite crowded when I went since it was free, it wasn't overcrowded where I was not able to do everything I wanted to do. I've heard they have adult only nights on Thursdays, I will definitely be checking the Exploratorium again on one of those evenings.
