@degroof Diffusion of milk in coffee or tea remains one of my favourite visual phenomena. Sometimes also tea in water: the trick is to dip the teabag slowly, so it doesn't get inflated with air and falls to the bottom, where it releases the tea at the bottom. After a couple of minutes, you need to pull the teabag up, and the beautiful diffusion begins.

@Krazov @degroof yeah I feel sad for folks who take their coffee black

@kinsale42 @degroof I have been taking my coffee black for years now, and I prefer the taste of black coffee. :P But, during winter, I brew caramel tea with milk, because it tastes like pudding that I remember from my time as a kiddo, and the diffusion is my favourite part.
