Anti-centrifugal effect

  1. Mar 8, 2010 #1
    I have a pot with water and some large particles lying on the bottom. When I stirr the water in a circular motion and then let the particles settle, they all gather in the center of the pot. Why is that so?

    Thanks for the solution!

    Btw, that reminds me of another simpler effect: Apparently when a van with helium balloons accelerates, the ballons move to the front :) Bouyancy I suppose.
