Teasing John for copying his recent formats, Hank takes him behind the scenes of the Monterey Bay Aquarium's deep-sea exhibit, explaining that its effortless look hides a precarious system that turns bay water into low-oxygen deep-sea water, and praises aquariums for bringing other worlds to people.

What is said

The parts of the video and what is said in each (★ — how much it matters to the video).

00:00:00 — Hank teases John for copying his low-budget Bo Burnham and Google autofill videos and sets him a harder one to copy

  • ★★ Hank notes that for the last few videos John has copied whatever he did (low-budget Bo Burnham, a Google autofill video) and calls it cheating, or at least lazy. (playful) — 00:00:03 · John Green
  • ★★ To make it hard for John to copy him, Hank takes him behind the scenes of one of the most advanced aquarium exhibits in the world. (playful) — 00:00:03 · John Green
  • ★★ Hank says he got to tour the exhibit before it existed, to see the complexity of what makes it come together. — 00:00:03

00:00:34 — Why deep-sea animals are hard to show, and how the Monterey Bay Aquarium exhibit simulates deep-sea water by removing oxygen

  • ★ Hank says an aquarium is more complicated than pumping in seawater and adding fish, and that he made a whole video about it three years ago. — 00:00:34
  • ★★ Hank says the ocean differs greatly with depth, and deep-sea animals are seen by basically no one because the deep sea is extremely hard to reach. — 00:00:34
  • ★★ Hank says deep-sea animals are hard to bring to the surface, and surface seawater is so different from deep-sea water that they cannot survive in it. — 00:00:34
  • ★★ Hank says the Monterey Bay Aquarium's exhibit lets visitors walk in the dark through halls surrounded by deep-sea animals, designed to feel effortless rather than to explain the engineering. — 00:01:03
  • ★ Hank says he has not yet been able to visit the finished exhibit. — 00:01:03
  • ★★★ Hank says that before the exhibit opened he saw that the seemingly effortless cohabitation of humans and deep-sea animals is actually extremely complicated and fairly precarious. — 00:01:32
  • ★★ Hank says the pressure difference between the bottom and top of the sea is bigger than the difference between air pressure at sea level and in space. — 00:02:01
  • ★★ Hank expected pressurizing the water to be the hardest part, but many deep-sea creatures hold little gas, so brought up slowly they are fine and the water need not be pressurized. — 00:02:01
  • ★★★ Hank says the real trouble is that deep-sea water itself differs: higher salinity, a consistently low temperature and very different gas concentrations. — 00:02:01
  • ★★ Hank says systems behind every wall of the exhibit take water from Monterey Bay and turn it into a simulation of deep-sea water. — 00:02:30
  • ★★★ Hank says the hardest part is removing just the right amount of oxygen: it is very reactive, and surface-level oxygen would kill many of these animals used to very low concentrations. — 00:02:30
  • ★★ Hank says all the aquarium's water runs through equipment designed for semiconductor and pharmaceutical manufacturing, where chemical levels must be tightly controlled. — 00:03:00
  • ★★ Hank says the water runs over many thin-membrane straws with very low pressure inside, so the oxygen is sucked out toward the lower-oxygen area. — 00:03:00
  • ★★ Hank says they cannot remove too much oxygen or the animals will asphyxiate, so it must be balanced every hour of every day. — 00:03:00

00:03:29 — Leaving the deep sea to researchers; aquariums bring other worlds to people to inspire wonder; sign-off

  • ★★ Hank says he cannot go to the deep sea and probably shouldn't, leaving it to researchers dedicated to understanding and protecting it. (hedged) — 00:03:29
  • ★★★ Hank praises the Monterey Bay Aquarium and places like it for working hard to bring those other worlds within our own to as many people as possible, inspiring wonder at the planet and human ingenuity. — 00:03:29

In the description and comments

  • ★★ The description says it is ridiculous that the deep sea can be brought up for people to walk among, and Hank loves aquariums so much. — video description
  • ★ The description says the aquarium is about two hours south of San Francisco and partners with the Monterey Bay Aquarium Research Institute, which did most of the collections for Into the Deep. — video description
