Jacques de Vaucanson exhibited this copper duck in Paris. It could flap its wings (each containing over 400 moving parts), stretch its neck, drink water, eat grain, and appear to digest and excrete it.
The duck was a sensation. Voltaire wrote that without it, "there would be nothing to remind us of the glory of France." It toured Europe for decades.
The "digestion" was a trick — pre-loaded dyed breadcrumbs were expelled. But the wing mechanism was genuine, each feather individually articulated by cams.
