We were kind of concerned about how the kid's would do. Would they be interested in it? Would they run around and not pay attention to any of it? In fact, they loved it! We all had a fabulous time. They were interested in things, we got to look around and actually enjoy ourselves. I think all the years of taking our littles everywhere are really paying off for us. They still talk about going and want to go back. It's just the right amount of weird, gross, fun, hands on stuff. My daughter's favorite part was the piano stairs. But I think the guy that looks like a snake was a close second. But I'm not going to give away much more. You'll just have to check out. And if you aren't in Baltimore see if there's a Ripley's near you! Make sure you stop by to grab a wax hand. It was well worth the wait (on the weekend there's birthday parties!) and my kids just love looking at their little hands.
