I don't know how that's possible. I still love to play with all the interactive exhibits. Fifteen years ago, most everything was mechanical. A lot of that is still there but every area has been updated with new displays, entirely new exhibit rooms, interactive computer touch screens, and simulator rides. There is also a full size elephant and giant shark.
The Museum of Discovery and Science is an excellent destination to introduce your children to science and discover a day's worth of fun for the whole family.
