Automated fun.
Start with the boring stuff first here and then spend the rest of the day just puttering along with the hands on stuff (although the boring stuff may not be seen as boring). We walked the wall that had the Robot Hall of Fame and ended up at the photo booth bench thing at the end. The photo op area is by far the best thing in this little section. You pick up to six robots you want in the picture with you and a background and wait for the picture to be taken. After the picture is taken you have the choice to put in your email address and have it mailed to you, or you can just forget about it.
Then the fun begins, you go from section to section to see if you can outwit the robots. You could easily waste all your time here in this one part of the science center. There are tons to do here, but for me to list them all would leave nothing to be discovered. You just need to experience it yourself.
