Hot and cold water sound different when you pour them. When Steve pitched this to me, I didn’t believe it, and then he sent me a couple of sound files, at which point I knew this was going to be the first of the guest videos!
In the video, science presenter Steve Mould explains why human ears are almost as potent as dog ear’s. Just kidding — we’re not quite there yet, but we’re still proud of this information nonetheless.
Anyway, Mould starts by letting us hear the sound of both cold and hot water pouring. As it turns out, there’s an obvious difference in the sound between the two, which has to do with the water’s viscosity, or thickness.
So basically, all of this came about because, over time, our ears adapt to hearing different cold and hot drinks being poured. That means we’re instinctively in tune with with what’s hot and what’s not.
