The very best children's science center we've ever been to! We live 2 hours away. We went because we were visiting family in Lansing for the weekend. I would definitely drive just for this place! We spent 5 hours there with my 3 yr old son and 6 year old nephew, and we still didn't even see 1/2 of the place!
So so so many things to try out, touch, experience. Friendly staff. Super clean and we'll kept building.
I was very impressed!
