Cool spot to entertain kids away from the typical OC stuff and Disneyland. Educational and informational, it's got some cool standard exhibits that are almost all hands on for kids. Special exhibits run a couple months at a time, we just missed out on the ninja turtles exhibit.
Kids learned about waves, air, steam, vacuums, hydrodynamics, hockey, grocery/shopping, insects and chemistry.
We spent about 4 hours there which is about right.
Another bonus is it's a membership institution for our museum back home so we got in free.
Check it out.
