Hey, I just went to see the Dinosaur exhibition a few days back. In doing so, I also visited the Science Centre.
I am surprised to find that many of the exhibits I saw when I was young, about 20 years ago were no longer there. I could not remember seeing before the things I saw there today. For example, I remembered there was a hot air balloon demostration some 20 years ago but I couldn't find it a few days ago. Likewise, there was an exhibit that demostrated how light energy can be converted to fan energy but I could also not find it.
Did they change the exhibits? It was like a new science centre to me.
