At what time do the exhibits come to life?

I stayed their all night with the cub scouts and they never did. lol

After closing time when everyone else has left. It has never been possible to document it.

I believe they do but I'm not sure what time.

They have a live butterfly and big exhibit if that counts.

The circling Indians might😎

Some of them do, there are hidden buttons for a few of them....

Depending on what exhibit, as soon as you get near an interactive part of it.

I believe the "come to life" has already passed. I would call for clarification and to ask when the next one will be.

after sunset

Only during a full moon.
