We have several walnut trees on our church grounds. California crows love the meat of the walnut. How can a crow crack a walnut to get at the meat? Imagine if you were a crow-how would you do it? The crows have figured out a way. They pick the walnut up in their bills, fly high over our church parking lot, and let the nuts fall on the hard surface! The walnuts crack-and the clever birds swoop down and eat the meat! If a crow's brain can find a solution to its problem, surely you'll be able to solve yours.
