A friend suggested we check out the Discovery Comminications (as in the Discovery Channel) building in Silver Spring and boy was it a hit. You can tell by the excitement in Chase's face, right? We watched those balls wind, spin, drop, and jump through the exhibit for 20 minutes. That's equal to two months in the life of a three year old. I have to say, I was pretty entertained myself. The $0.50 paid for the visit (meter money) was totally worth it.
