1320 Balancing Bird
This simple device demonstrates how gravity works. By perfectly distributing weight on the tips of the wings, and placing its mass near the tip of its beak, the equilibrium of the bird is stabilized. This allows the bird to balance on whatever object it is placed upon! 6" x 6" x 2.5", 0.1 lb.
