Science!

 Cambridge has an awesome science festival every year. We saw neighbors, friends, and lots of people we knew there; it was the place to be.

 Phoebe drove some underwater robots. Bruce burned holes in paper with a magnifying glass.

 Phoebe mixed up a quick polymer material in a paper cup. Bruce built a specialized racing car out of Legos that could go down a bumpy track.

 After the science festival, we stopped at the library next door. We love the libraries here.

But sometimes the books put us to sleep....
