>put ice cube in hot coffee
>it floats to one side
>the coffee grounds in the bottom of the glass move to the opposite side in a pile
What is the scientific basis behind this?
Physics

That's pretty cool, make a video you weaboo faggot.
>>8476458
How would you see that? Also it is the cold water flowing to the bottom.

Why does physics exist? Idk man
>>8476481
cold water is actually denser than warm water, it only becomes less dense when it freezes
the cool water flows downward because it is denser, and the coffee grounds get swept by the current
also wtf why would you leave coffee grounds in your coffee
>ice cubes in coffee
Wat

Easy way to make iced coffee
>>8476694
If you want watery iced coffee. Either fridge your coffee or coldbrew.
>>8476693
I brew coffee with 90C water, it too hot to drink at that temp. One ice cube quickly cools it down to drinkable levels.
>>8476458
that's called convection.
Now you can try to imagine a coffe with an infinite Prandlt number and a Raleigh number of 106, your Ice cube as a continental plate and your ground cofee as a LLSVP, and you'll have Earth mantle.
(actually, no, it's far more complex than that)

*10^6, not 106, ofc
