Uhoh! Brennan on a lightly competitive game show

[ladytara]

watching Brennan's instinct to be right war with his instinct to be funny

[LincolnDWard]

Geology major here – the general term for "there should be rock here but there isn't" is a *void.* These can include cavities, chambers, caverns, fissures, channels, pores, bubbles, tunnels, tubes, and of course caves.

[velocikate]

"Whale, Whale, Irene Adler" killed me 😂 Listening to Ceri and Brennan get silly and frustrate Hank was comedy gold!

[lanidickens]

Can i recommend a guest? Cause if so, ya'll should invite Caitlyn Doughty, AskAMortician. She'd be delightful competing with her weird facts.

[LITMasonEdits]

this really felt like hank trying to babysit two teenagers who cant stop making each other laugh. truly a substitute teacher losing control of his class vibe

[australobuchia]

Excited geologist here, Holes in rocks have lots of different and sometimes overlapping names because there's so many different reasons for them to exist! The most all encompassing terms I can think of are "Cavity" and "Void". They could be used for microscopic holes or a hole big enough to put a building in. mm to cm sized holes might be called a "vug" or a "vesicle" depending on the cause. Sometimes we might just say "Air bubble" also can be this size and smaller. I actually think defining Cave as a hole large enough for a person is a pretty good definition. Cavern definitely implies a space large enough for many people standing up and possibly buildings. As mentioned by someone else, we often name things in relation to how the cavity was created. Lava tubes (formed by the lava hardening on the outside but continuing to flow on the inside) can be large enough to fit people and therefore can sometimes be traversed by spelunkers but also sometimes they aren't. So a lava tube can be a cave using our person size definition but isn't always. The term karst system is used only for cave systems in soluble rock like limestone etc. because the landforms created by the dissolution of the rock are very particular (and spectacular). Naming taxonomies are hard, people 😂

[jennifersaar]

Hank's actually right with the animal cave! One exists (albeit a small one). There's a rhino cave in the state of Washington that was created when lava cooled and hardened around the body.

[emilys]

as an askamortician fan I was SCREAMING "devils hole pupfish!!!!" the whole time

[IceMetalPunk]

Brennan?! On Tangents, you say?! FOR SPOOKY SEASON?! There is zero way this could be better except whY ISN'T IT HERE YET?! 😅🎃

rhyming subterranean with "terrain he's in" is genius.

Brennan slipping into the Citizen Doctor Abraham Mehemblur voice is absolutely sending me. Iconic. And perfect for spooky season!

[moonbeast]

22:10 "You think you are too good to die in cave? Wrong."

[honeyfrost_vt]

As soon as hank said that the creature didn't move for 7 years I was chanting "OLM! OLM! OLM! OLM!" like it was my favorite sports team

[ashutoshadh]
