One thing that my parents did an excellent job of was instilling the seed of wonderment and curiosity in both me and my siblings. They took us to the Art Center , Art in the Park, and the Science Center. Every year, my dad would take me to an independent theater to watch an animation festival. In fact, the elementary school that we attended was Edmunds Academy of Fine Arts. I think that these all helped build a foundation of appreciation for not only the Arts, but for general knowledge and the expansion of our mental horizons.
When I was younger, one thing that I looked forward to every Thanksgiving was a similar experiment to the rubber egg. But instead of a rubber egg, you ended up with a wishbone that you could tie in a knot. When it dried, you had a bone-hard knot. I would take the hardened bone to school and baffle other kids. It was almost as if it was a magic trick.
