Had enough art while you've been in Winterthur? What about a science session? Technorama is an extraordinary voyage into the multiple worlds of hands-on science. Encompassing four jam-packed floors of exhibits, it offers some 500 interactive experiences (explained in English, French, German and Italian) that can’t fail to fascinate kids, and plenty of adults too.
