COSI is great! The museum is huge and our kids are always fully entertained and learn for hours. They have a gadget cafe where you can grab a table and "servers" will bring you different "courses" which are a variety of science experiments the whole group can work on together. Every few feet you'll run into engaging, interactive exhibits supported by friendly staff. There are lots and lots of unique things to do. There is also a large address for small kids, an outdoor area, and a stage for demonstrations.
