The Way Things Work - Floating
In Floating, inhabitants of Mammoth Island attempt to rescue an islander and his mammoths from the middle of a lake. They are stranded on a small island after a wooden bridge collapses. Olive, a bright young islander, notices that the wood from the broken bridge is floating on the surface of the lake. With the help of a visiting inventor, she discovers the principle of buoyancy. Every object exerts a downward force on the water, and the water pushes back with an upward force on the object. When the buoyant force is greater than an object’s weight, the object floats!
