When I was a little boy, I asked my mother what hair was made of. She tried to explain it to me in a way that would make sense to a six year-old, but remain scientifically accurate. Hair, she said, is made out of protein. I asked "What's protein?" This proved to be an even more difficult topic, but she did say, at some point, that peanut butter was rich in protein. So, as I understood it, hair is made out of peanut butter. I responded by making a hair and jelly sandwich.
It was awful.
But that's what happens when kids try to understand the adult world around them. An artist named Pierrette Diaz composed a set of paintings that works with that theme, visualizing what kids misunderstand.
