First stop - the Sea Lions at Pier 39.

Then off to the Exploratorium.

It is full of interesting things!

Ella puts her hand through a bubble-wall.

The top floor has a weather station overlooking the bay.

Ella plays with a freezing table (that quickly makes ice).

Looking at the ice through a polarized lens brings out some cool colors.

Ella checks us out in a large concave mirror.

Somem final views of the harbor.
