“I want to emphasize that light comes in this form- particles. It is very important to know that light behaves like particles, especially for those of you who have gone school, where you were probably told something about light behaving waves. I’m telling you the way it does behave- like particles.”
Richard Feynman, “QED: The Strange Theory of Light and Matter”, pg 15
I tried the same thing. I had my daughter watch Spirited Away when she was maybe 6. It traumatized her. She was scared of us turning into pigs and being left alone.
