For those who've been to science museums (or even normal museums) before and enjoyed the experience, what kind of exhibits were effective or fun or left an impression on your mind?
eg. I can remember an earthquake ride from when I was about 8, I remember a lightning machine that made real lightning and also I remember a really, really viscous fluid in a container that was going to reach the bottom of the container in about 1997.
I'm trying to see what works and what doesn't. If you haven't been to a science museum, then off you go... I'll wait for your reply.
