Rating science museums

The day before yesterday we went to the science museum in Warsaw.(We always have to go to the science museums that are within 500 kilometres radius). There's only one that doesn't obey the law the Egyptian science museum we never went to that one. But there's probably those of you who have.This is my rating of the science museum (especially at 10.00 to 04.00. (There are crowds at this time)
******=6.
