Love this place! We have come here a couple times now when we were visiting family & it was totally worth the trip (it's an hour drive). There was so much to do & see for every age level. We spent a lot of time playing in the water table last year when our son was only 19 months. This year at almost 3, he was able to do a lot more so we got to bang on the drums, build monsters & play with the vacuum tubes (which were his favorite). They had an exhibit with Frogs while we were there & I was really impressed with it - there were some cool camouflage frogs we had never seen or heard of before.
They have a lot of hands on activities for older kids as well (there was a build your own shoe with duct tape &/or tin foil) as well as a light show that looked like a dance party for kids.
We will definitely visit next time we are in town.
