Museums have changed.  They are no longer places for the privileged few or for bored vacationers to visit on rainy days.  Action and democracy are words used in descriptions of museums now.
    At a science museum in Ontario,  Canada, you can feel your hair stand on end as harmless electricity passes through your body.  At the Metropolitan Museum of Art in New York City, you can look at 17th century instruments while listening to their music.  As these examples show, museums are reaching out to new audiences, particularly the young, the poor and the less educated members of the population.  As a result, attendance is increasing.
    More and more, museum directors are realizing that people learn best when they can somehow become part of what they are seeing.  The visitor is encouraged to touch, listen, operate, and experiment so as to discover scientific principles for himself.  He can have the experience of operating a spaceship or a computer.  He can experiment with glass blowing and paper making.  The purpose is not only to provide fun but also to help people feel at home in the world of science.  The theory is that people who do not understand science will probably fear it, and those who fear science will not use it to best advantage.  Many museums now provide educational services and children’s departments.  In addition to the usual displays, they also offer film showings and dance programs.  Instead of being places that one "should" visit, they are places to enjoy.
