How many licks would it take? Can the iron in bars even be processed by the body? Can you do this for other minerals?

    A little cat iron puck was introduced in an Asian region with high iron-deficiecy in the poorer population, but nobody used it. So they did some research and changed it to resemble a fish instead and it took right off. Turns out the local culture considered fish lucky or something.
