I have a friend whose family loves all factory tours. If there is a factory open to the public, she and her family are there. Perhaps it is the bad childhood memories of long and boring factory tours where the only upside was getting free samples, but, in general, I do not get excited about seeing assembly lines and learning some useless facts about any product - food or otherwise. That said, the Coca Cola factory tour in Bnei Brak is actually a lot of fun for both adults and children.
This may be due to the fact that the tour is very commercialized and done up and actually spends little time viewing the actual factory and a lot more time selling the product; in any case, there are lots of fun things to see and do as you move from room to room filled with lights and sounds and interactive games. And you even learn a fact or two about Coca Cola. The tour is recommended for ages eight and up and is appealing for all ages.
