There actually used to be a very interesting science museum in Brussels called Scientastic [1].

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.
