this toy, flapping wings, is based on the crank. as the crank moves round and round,
the bird flaps its wings. the body of the bird can be removed and now you can see the
crank mechanism more clearly. its made of three straws, wire, etc. you can see that
the two straws are hinged at the bottom in the shape of a wheel. and as you crank the
handle round and round. the wings flap. here you can see the bottom view and now the side
view, how the wings have been attached. and now you put the body together. now the bird
is all assembled and then you can house this bird in a nest, a small paper cup.. now when
you rotate the crank, this bird flaps its wings beautifully and gracefully.
