Really interesting exhibit that I recommend with some hesitation. I went on a free day which meant the lines were insane. It took a full 3 hours from the time I got in the door to get out of the exhibit. There's no way you can really jump ahead as they have such timed parts so if you wanted to leave early, you would have to go out the emergency exits. On a normal day, I can see that it would be much more relaxing and less stressful but if it is super busy, I would say skip it and come back when there are less people. The price is quite high for one exhibit and it isn't terribly interactive for kids...there's a lot for them to see, but not a lot to do. Not great for little ones except for the soft play area which costs extra.
