I graduated college with a degree in Physics, so I'm kind of like a kid in a candy store here. My kids are old enough to find most of this interesting or they like learning from Daddy. We have a membership and we go right when it opens and shut it down. My kids favorite part is the Alice in Wonderland room and they can spend a long time in there, followed by the spinning gazebo thing that simulates how the goldfish feel when they people push a button and make their environment spin around. It gets busy on the weekends and that also teaches my kids to take turns with other children.
