How long does the exhibit take? 2 hours? 5 hours? Half an hour? As long as you want it to? I have a friend that has to work a few hours after our ticket time & debating if she could still go...

It is at your own pace but probable about an hour or so.

We have 2 teenagers, they go fast for our tastes and spent an hour...two would have been preferred

You can go as long as you would like! There is no guided tour. You just do your own thing.

I spent 2hrs there. But she can leave whenever she has to.

It's a self guided tour as long as you want.

Self guided. If it's busy it will take longer. Suggest planning 1.5 hours plus or minus 30 minutes.

Takes about an hour or less but you could spend more time in there if you want

Hello, Thanks for reaching out. The exhibit can take up to 75 mins., but the last entry time is at 19 hrs.- Let us know for any further doubts. Regards!
