[[Helen's sister, Helen, and their mother sit at the kitchen table. Sister asks a question; Helen eats her breakfast; their mother reads the news paper.]]
Sister: Mom, why is the sky blue?
Helen: I got this one.
[[Close-up on Helen's face and torso. Very anime-like expressions on all of the characters.]]
Helen: Okay, you've played with a prism, so you know light can be split into colors, right? Well, when light hits something like dust or molecules, the blue gets more scattered than the red. So when light from the sun is passing overhead, it hits stuff, and the blue light comes down into our eyes, and that's why the sky is blue. Make sense?
[[Close up on sister.]]
Sister: Actually, I knew all that. I just wanted to make her squirm.
[[Back to original view of all three characters.]]
Sister: So Mom, where do babies come from?
Mother: We'll see how smug you two are once you've been out of school as long as I have.
