Third grade scientists observed Drinking Bird and tried to determine the science behind the movement. Watch the video first to see if you can determine what is happening.  Click here to watch our Drinking Bird.

I dipped the bird’s beak into the water. As the water evaporates and the head cools, fluid moves up into the head, causing the bird to become top-heavy and dip forward. Once the bird dips forward, fluid moves back into the abdomen, causing the bird to become bottom-heavy and tip up.
