Have you ever tried to do this?
Give students a small ball of clay and ask them to hold it between thumb
and index finger. Then challenge them to squeeze in a manner that will
make the two sides not come out symmetrical. It is a convincing effort.
I wish I had remembered it in class today, maybr tommorrow.
