We walked around the carpet, following the story of Samra. The Duck Machine was in the back corner, an odd contraption with a lever that looked like a duck-bill and a bird floating inside the plastic tub.
“You quack into it,” the guide explained.
I did, and the duck burst to life, flapping its wings, wiggling its way out through the duck-bill opening, almost attacking me, flying at the peanut machine. The machine took pennies, which I fed it, and peanuts shot out, except that the duck was no longer a duck but an otter or a marten, something like that, and dove out of sight, now more of a snake. I still had two pennies left.
“That is the story of Samra,” the guide explained. “First one thing and then another.”
