ELI5: Why is it so hard to use your fingers to pick something small out of a drink?
gpt
You know how when you plonk a rock into a lake, it creates those circles of little waves moving outwards? Those little waves like to push things away from the middle of the circle.

In this instance, your finger is the rock and the 'something small' you're trying to fish out is being pushed away by the little waves made by plonking your finger into your drink.
