Does tint in a water glass move randomly?

310 viewsOtherPhysics

If we let a tint drop fall into a glass of water, it looks like it spreads randomly.

But let’s they we could repeat the experiment under the exact same conditions (with the same glass, water volume, arrangement of water molecules, amount of tint, fall height and everything that could affect the equation). Would the tint drop spread exactly the same or would it still be random? Do we have any knowledge about the correlation of time and matter in an theoretical experiment like this?

Yes. Think of the water and the tint as a bunch of tiny, invisible ants moving around. The ants don’t have a specific plan or direction; they just walk around randomly. When you drop the tint into the water, there are lots of “ants” in one spot. As they move around, they spread out to places with fewer ants, spreading the color with them.
