Went there with my grandchildren, aged 11, 9, and 7 years. They had a very good time. There was a lot to keep them interested and busy. Unfortunately not every thing was operational. In one exhibit there was a large hoop in which they could step into and encase themselves in a bubble. However that did not happen. We were told the soapy solution was flat. It gets changed once a week on Sundays. We were there on a Saturday. There were wind turbines to test the impact different shaped fan blades have on the turbine's speed. The pegs on the blades were worn out and fell out of the turbines. The outdoors Discovery Center that stuff for climbing. The whisper dishes did not work.
