Sound of stirring

This morning I made a mug of tea.

An hour later I made mug of coffee.

I noticed that the sound of stirring the two drinks was different.

Anyone know why this is?

Seems strange that I used the same mug, but the sound of the stirring was different depending on the drink.

What's so different about tea with milk, versus sugar with milk?

There was no teabags in the tea by the way.

I don't have a scientific explanation, but have noticed something similar.

Stirring coffee, the sound is duller than stirring tea. The sound is clearest when stirring plain tea without milk.

Thickness of the liquid?

Temperature might be a factor as well.

Tea with milk, now that sounds weird

Viscosity and resistance in the liquid I presume , the coffee dissolves in the water increasing the viscosity , the tea leaves don't , only the tiny flavour molecules from the tea which don't appreciably increase the viscosity ..........in case you haven't guessed I'm only winging it here ,any theoretical physicists on here ? Or all you all pondering the mysteries of 'life the universe and everything '? ....or hungover .

Apparently there's more caffeine in a mug of coffee than there is in a mug of tea, so the molecules in the coffee would be more agitated, thus affecting the structural integrity of the liquid. That could account for the different sound.

Pondering the lack of viscosity of their bodily emissions I'd say.

This sounds highly plausible.

Yeah to the recycling bin.

My guess would be due to the difference in viscosity and density between the two different liquids. The amount of contact between the spoon and liquid, and the liquid and cup may also come into play. Another big enough factor is the amount of liquid in the cup. Were they both filled to the exact same height? If not, the amount of interference experienced by the sound as it travels up through the cup may have a noticeable affect!

Not in after hours. This is just for us gob****es. Welcome.

Most likely you had ear plugs in while tea making and not when coffee making.

Its just one of those things we're not ment to know.Like why is the earth flat...

Density of the liquid will affect the speed at which sound will pass through it, and as such, alter the pitch of the sound emitted. However a bigger factor is the fact that you more than likely used instant coffee - tiny air bubbles are released from the coffee grains into the liquid, and as sound waves travel a lot more slowly through air than they do through liquid, it affects the pitch of the sound emitted.

With tea, you're really just stirring water because the tea bag keeps its contents in the bag. With coffee you're actually mixing coffee into the water and making it more dense. Yeah, science.
