Have you ever struggled with a drumstick when they’ve served chicken at school? You take a bite and chew … and chew … and chew. After you’ve finally managed to swallow it you feel the need to come up for air before trying another bite. You need stamina for this sort of meal, after all. That’s when you begin to wonder whether you’ve been eating a rubber chicken rather than a real one. Then you think, „That’s ridiculous! Who ever heard of a rubber chicken?” Try this experiment and you might begin to think otherwise.
