Description:
|
As the liquid
evaporates from the head of the duck, the liquid in the duck heats up
(towards room temp) making it rise up the duck's body. When it passes
the CM point of the duck, it tips it over, getting the beak wet again.
The cool water cools the liquid and the duck stands back up.
