Today I had to make Linnea a model of the human eyeball and demonstrate pupil dilation in different light levels. I made a ring of my hands and showed how the iris works, and looked at "the dark inside my hands" and the light outside the window so she could see different pupil sizes. She was interested, made her own models, drew some diagrams, and said she didn't WANT a pupil any more because she wanted eyes with no holes in.
