Weitzman's Institute in Rechovot

I would like to recommend an activity suitable for the 9 days of Av; a visit to the Weitzman's Institute in Rechovot. At the Institute, there is a visitor's center suitable to for adults and children 12 years or more. One should devote about an hour to view the center. Nearby there is a Science Garden that is suitable for all from the age of 6. The garden can provide activities for many hours. It is most recommended to visit the Marine World exhibit there in addition to experiencing the many apparatus that demonstrate various scientific principles and phenomena. Additional nearby sites are the Ayalon Institute,
