Science museums have a reputation as being places to bring the kids. The Exploratorium, now located on the Embarcadero, defies this. It lures passersby, regardless of age, to its building with the bizarre contraptions and “let me get a closer look at that” devices outside its door - a bicycle dangling from a post that has been contorted into a horn, for example. Once inside, the place is interactive magic, exploring human behavior, the biological world, and your own senses. On Thursday evenings, the doors close to children and the bartenders pour drinks in the cafe for After Dark - a popular date-night choice.
