The museum was aimed at children and the exhibit consisted of many practical "magic tricks" illustrating some piece of science or technology. Things such as electromagnets, refraction effects, color theory, optical illusions, simple mechanical devices, simple chemistry experiments, etc. For example I remember first learning about the brachistochrone curve at this museum, even though I was too young at the time to know or care about its name. Or that you could use red cabbage juice as a natural pH indicator.
Unfortunately the museum never got much funding or interest from the government, and at some point the museum was destroyed (possibly illegally) to make room for a shopping mall.
Looking back on it, I find it funny that out of all the amazing things there (a full sized rocket, some kind of capsule you could actually sit in and play with the controls on), the thing that continually fascinated me the most was a little audio visualiser with a microphone, so when you spoke into it the line would deform.
There are plenty museums full of cool stuff that's either interesting them, or can be played with, or are outdoors and can be handled as just a pleasant walk through a cool looking place.
