Watching Swans feeding a few evenings ago and saw this curious phenomenon. When the Swan dips its head into the water to feed it does it so smoothly and quickly and its head is so designed that it doesn't create a splash but appears to push the surface of the water down into a "dent" which then refills with water pouring in from the edges. I presume this is an effect of surface tension. Has anyone else noticed it or can anyone explain the underlying physics?
