#1818: Rayleigh Scattering
[Science Girl asks Blondie a question which she answers while lifting her arm towards Science Girl.]
Science Girl: Why is the sky blue?
Blondie: Because air is blue.
[Megan walks in from behind Science Girl.]
Megan: No, the sky is blue because of Rayleigh scattering–
Blondie: Nah, it’s because air is blue. Blue light bounces off it and hits our eyes. Same as why anything is any color.
[Zoom in on Blondie’s face.]
Blondie: It’s why far-off mountains look blue – because of all the blue air in the way.
[Zoom out to Megan standing longer from Science Girl than Blondie who has thrown her arms out. Science Girl is facing directly out towards the reader.]
Megan: There’s a specific quantum mechanism by which–
Blondie: Yeah but there’s a physics mechanism for every color. You don’t have to get all quantum right away.
[Frameless panel with Science Girl looking up at Blondie who stands holding her hands on her sides. Megan speaks from off-panel.]
Megan (off-panel): …OK, I guess.
Blondie: Any other questions?
Science Girl: How do planes stay up?
[Blondie holds a finger up in front of Science Girl while Megan now is the one to throw out her arms.]
Megan: Well, the airflow–
Blondie: Tiny birds in the wings. Thousands. Flapping hard.
Science Girl: WOW!
