Just went to the pirate exhibit this weekend and I want to write a review because it was by far the coolest one yet.  I have been to the body exhibit, the titanic exhibit and others there.  Of course there is more to do there than just that for the kids, they blow stuff up at the lab, they have tons of cool little sections with things to do.  It is not cheap but we got the annual pass for the exhibits this year since we did the maze and we wanted to come back for the pirate and the Van Gogh exhibit coming next.  Now back to the pirate exhibit, holy cow they had a real life pirates treasure at the end that was valued at 400 million dollars!  The have tons of real \""pieces of 8\"" they also recovered the bell from the original ship they found off the cost of Cape Cod.  There was their silverware, belt buckles, guns, cannons, gold, silver, rope, and I can go on forever.  It was just super cool to hear the story and see all the real life stuff.  This is not just a kid exhibit and in fact I spent much more time reading things and my kids blew right through it.
