This morning, we headed over to the Museum of Science and Industry to spend some time in the Idea Factory. This is a great spot for little ones. It is like a mini version of the Chicago Children's Museum (plus you have all of the other great MSI attractions when your little museum-goers are ready to move on to something else).
A few words of warning: The Idea Factory can get really crowded -- and when that happens, there are only so many people allowed in at a time. There will be signs posted so you know when to come back for the next entry time. Also, many of the activities in the Idea Factory involve water. They do have some smocks available -- but not nearly enough for every kid. So you might want to throw an extra set of clothes in your bag for little ones who won't be able to resist dunking their entire arm into the water to retrieve the brightly-colored balls bobbing by. Also, the signs say that the space is for kids age 10 and under, but I thought that most of the activities were really for kids more like age 8 and under (just my opinion).
Here are a few photos from our time at the Idea Factory this morning so you can get a better idea of all of the fun to be had. By the way, the Museum of Science and Industry is free through Friday, June 11th (and you can check out more upcoming free museum days here).
