when i stir a cup of tea, the floating tea leaves go to the center of the cup, but also sugar at the bottom of the cup goes to the center. what is the principle here how does it work.
Its due to the spoon being fat at the bottom of the cup and thin at the top. When you stir the spoon is on the edge of the cup as soon as you take the spoon out the tea slows and the leaves start to work it's way to the edge
