We have a short show for you today. I'm on my way out of town, but I'll be here.

Mike will be here alone, but we do have a how-to for you and I was reading recently about the human ear.

And one thing that it said in this article

is that the human ear is so remarkable

it can detect the difference between the sound of hot water being poured into a glass

And cold water being poured into a glass

And we wondered why that is. So on the line with this now is Charles Spence. He's an experimental psychologist at Oxford.

He studies this stuff. So Charles what what's going on there so the reason I think

why hot and cold drinks sound very different

uh... to do with temperature and what happens is that a

a drink of a different temperature have a different kind of

viscosity and so you will hear that change in the viscosity

of the liquid that you're pouring

to kind of having different pitch in a hot drink from of the

different pitch and a hot drink from the stages that are freshly boiled kettle

when you pour it or will sound sort of lower in pitch

whereas a ice cold water say from a jug that's been sitting there in the

fridge, will sound kind of quicker in pitch instead.

And it's amazing, I mean I think that, you know, if I were blindfolded and I heard the sound of cold water being poured into a glass,

it would make me thirsty for that in a way that the sound of you know hot coffee would stimulate something else.

That's right to say it may be, I think there's a sort of sound of you know, of opening bottles and

cams and containers and pouring are informative and they do have expectations
