The Springs Preserve has an exhibit that includes 40 life size inventions of Leonardo da Vinci. I wasn't sure how interested a 4.5 yeard old would be, but we went anyway. It was SO COOL! Alanna loved it and I wish we would have had more time to spend there.
It was so neat to see Alanna discovering and learning with these machines. And I especially loved that they were so hands on. We will be going back very soon.
