Exploratorium Popping Up All Around Town

All through January, Exploratorium Explainers will be popping up with cool demonstrations in SF locations such as Union Square, Ghirardelli Square, and Aquatic Park, bringing the Exploratorium’s signature blend of fun, science and participation to passers-by!

In their bright orange vests, Explainers will help you trace shadows, observe clouds, or offer up a quick lesson on perception by performing magic tricks.

The Explainers will tweet locations each week at http://twitter.com/theexplainers.
