Big Blue Blocks, an exhibit for open ended, creative play where kids build a new world every day. Using soft blocks of different sizes and shapes, you can make objects like tractors, animals, and robots or build imaginary places like houses or cities. You can build scenery and then play in it. There are no rules - kids decide what and how to play and there are no limits to their imagination. This explorative play is a lot of fun and you never have to build the same thing twice.
