Highlights

If you came from a country where the tap water was not potable... you're probably younger than me, but I remember when we went to continental Europe sometimes, we were told to only drink bottled water, and if you were a bit suspicious, the only way you'd know that the water you were drinking had definitely never come out of a tap would be if it was fizzy

00:05:23 · The host proposes a theory for why carbonated water is more common in certain regions.

So carbon dioxide sinks to the bottom of shafts, sinks to the bottom of wells. If you go down a well that's unventilated, you're going to die of asphyxiation.

00:11:42 · The host discusses the physical properties and dangers of carbon dioxide due to its density.

It's your chepping question. Oh, yes. It's from the old English word chepping, which means market.

00:18:03 · A caller provides the historical etymology for the term 'chippings' used in English place names.

And it comes from an old word called bugge. ... It was kind of a general term for some sort of spectre or something to do with kind of the fae.

00:37:04 · A caller explains the 15th-century linguistic origins of the word 'bogeyman'.

So think of it like a tequila sunrise. Yeah. So you've got the gradient in the bottom, which is with the carbon dioxide. You've got orange juice. You've got tequila, which is actually lighter.

00:43:47 · The speaker uses a cocktail analogy to explain how different densities prevent gases from mixing easily.
