Our visit to the Museum of Science today started with a showdown between Erica and one of the resident felines. I enjoyed resting in a perfect-sized chair while exploring an exhibit on perspective. The Electricity Theater was a big hit with Lily as were the interactive exhibits. I have been to the MoS many times and always look forward to discovering what’s new. On this visit, I was pleased to see an iRobot Roomba within the artificial intelligence exhibit as well as a robotic dog created by Boston Dynamics.
