Do hot and cold water make different sounds? QI Series N Episode 3: Preview - BBC Two

[DavidOakesMusic]

You know *instantly* if you pour the water from a kettle and you forgot to actually boil it. It just doesn't *sound* right.

[jackharding]

The next Slipknot album is just going to be ambient water noises now...

[MirageMusicUk]

I think She's a great replacement, also Corey weirdly fit into the show nicely, expected him to be out of his comfort zone a bit but he looked like he was loving it.

[LewisFoxhallSkuzzy]

Corey Taylor. Aisling Bea. Ross Noble. Someone's been reading my christmas list.

[MythicalSkull]

Weird not seeing Stephen but they found a great replacement

[BBoman]

I think the speed of sound through the liquid also affects the pitch, resulting in a higher pitch for hot liquids where sound travels faster. What I want to know is why the pitch continued to rise while the water was being poured for the hot water, while it descended as the cold water was poured. I would intuitively think that both should descend since the size of the resonator (i.e. the water level) is increasing, which should give a longer wavelength and, in turn, a lower pitch.

[TheNotoriousDUDE]

Corey Taylor was certainly not what I expected when I clicked on this video :'D

[Phlebas]

Sandi took over, eh?

Ah well. She was always one of my favourite panelists. Good choice.

[KishoreShenoy]

Can anyone tell me one of the songs Corey Taylor sings *before I forget*

[jamgrieve]

I didn't even realize that was Corey Taylor until the end.

[littlesnowflakepunk]

The second one has a lower pitch rising to a higher pitch, hot water has a more fizzy tone

[Jazz]

How many votes to abopt Cory Taylor as a Brit ?



Cause he was already in Dr who and now QI and he dose like it here .

[acolytetojippity]

i'm sorry, what? Corey Taylor is going to be on QI?

[NxDoyle]

It must be so ingrained, I've never given it a moment's thought*. I said 'hot' before the first playback of cold, then thought, 'Ooh, I should have waited for the next one', but it just confirmed that I'd made the correct decision.


*It might also be that I'm incurious.

[FirstOnRaceDayCapri]

Every morning i heat water in my microwave to make coffee and i instantly knew that is how hot water pouring sounds.

[luuketaylor]

Tom Scott's channel prepared me well for this.

[witext]

I’ve been trying to find a video where they test how the sound of water at many different temperatures but I can’t

[thenerdviewreview]

I do really like her but it's really going to take some getting used to it not being Stephen.

[rachelcookie]

I feel like it has something to do with her also saying “hot and cold” so you expect hot first. If the first one had been cold I feel like less people would of gotten it correct.

[grachogracho]

well tea with ~75°C or an coffee water in an boiler with ~98°C ;i mean i hear with my both ears less of
