Why is the Sky Blue and Other Questions Answered

2010-04-09 · Hank · watch on YouTube · Science & nature · explainer learning

Hank, claiming John is bad at science, makes a video for John's baby son a child of the brothers that pre-emptively answers a child's questions (rainbows, the blue sky, night, clouds, pain, flight) with real explanations mixed with jokes.

What is said

00:00:00 — Greeting to baby a child of the brothers; John is not good at science, so Hank pre-emptively answers his questions; Hank plays a child of the brothers in a hat

  • ★★★ Hank tells baby a child of the brothers that his dad John is not good at science and worries he can't answer a child of the brothers's questions, so they are answering them pre-emptively. (playful) — 00:00:09 · John Green

00:00:31 — What are rainbows? Why is the sky blue?

  • ★★ Hank explains that white light is many colors mashed together, which separate when light passes through water droplets, giving a rainbow. — 00:00:33
  • ★★ Hank explains the sky is blue because blue light, on hitting oxygen and nitrogen, bounces all around the atmosphere. — 00:00:47

00:01:02 — How does the internet work? (no idea beyond uploading to YouTube)

  • ★ Asked how the internet works, Hank says they upload videos to YouTube, people watch and sometimes email, and beyond that he has no idea. (playful) — 00:01:02 · YouTube

00:01:11 — Where does the sun go at night (Obi-Wan Kenobi's head as Earth)? How do clouds stay up?

  • ★★ Using Obi-Wan Kenobi's head as Earth and his lightsaber as the sun, Hank explains night: the Earth spins while the sun stays put, so we turn out of its light. — 00:01:11
  • ★★ Hank explains clouds are tiny water droplets blown around by air currents; a drop that grows big enough falls as rain. — 00:01:43

00:02:03 — Comic answers: hamburgers, babies, trees, dark hair, daddy screaming at cameras

  • ★★ With dark comic delivery, Hank says hamburgers come from calves taken from their mothers young, raised in confined animal feeding operations, then killed and ground up. (playful) — 00:02:03

00:02:42 — Why does fire hurt? Daddy's puffy hair; Horcrux; how do planes stay up?

  • ★★ Hank explains fire hurts because too much energy breaks the chemical bonds in your hands, and the body signals something is wrong, which is pain. — 00:02:42
  • ★★ Hank explains planes stay up because air over the curved top of the wing must travel faster than below, giving low pressure on top and high pressure underneath. — 00:03:11
    • number check: the air across the top has to travel faster than the air on the bottom — doubtful

00:03:31 — Why people do bad things; 'knocked up'; question time over; hope a child of the brothers becomes a scientist; sign-off

  • ★ Asked why people do bad things, Hank says it is not a science question, then answers: because their parents weren't as kind and loving as a child of the brothers's. (playful) — 00:03:31
  • ★ Hank hopes a child of the brothers learned a lot and becomes a little scientist like him; the genes must be in there somewhere. (playful) — 00:03:50

Humor (significant)

  • Hank explains to baby a child of the brothers why he, not John, will answer his questions. — 00:00:19 > «I am smart in the ways that your dad is stupid.»
  • Asked where hamburgers come from, Hank describes calves taken from their mothers, fattened in feedlots, killed and ground up. — 00:02:03 > «'Cause it's delicious.»
  • a child of the brothers (Hank in a hat) asks what a Horcrux is. — 00:03:09 > «Young man, where did you hear that word?»
  • a child of the brothers asks what 'getting knocked up' means. — 00:03:39 > «It's the- it's the opposite of getting knocked down.»
