Although, unlike most DC museums, entry is not free, the ISM is a good break from the weightiness of tourism in DC. The displays are interactive and fun, the subject matter has frisson, and whenever I see 4-8th graders there, they appear fascinated. I enjoyed it as well, as have all the visiting friends who have wanted to go there.

The museum is really cool. The design is modern and a bit eerie to fit in with the theme. I walked into the lobby and was intrigued. The price is a bit high, especially compared to all the other musuems that don't have admission fees (but do get government funding). The museum covers the "secret history of history" showing gadgets ...

If you have a half a day and you are in DC you should go here. Don't come last on a weekend because the line to get in gets very long.

A mixture of fun and educational history. Something for everyone.So much detailed information....if you love history and spy's this is the place to go. It was worth the trip and the price. We will go again soon to spend time with things we missed the first time.
