    3 pieces. Break a cookie in half 2 times.
    • Break #1: 1 = 0.5 + 0.5
    • Break #2: 1 = 0.5 + 0.25 + 0.25

    3 pieces. Not 4. You would need 3 breaks to get 4 pieces.

    You can't break a cookie in half twice. You can break it in half once and then you can break a half-cookie in half. Saying that you're breaking the [whole] cookie in half twice implies that you are making the first break and then breaking both of those halves in two.

    You guys need to get out more.

    It does not work for cars because cookies and rocks have a property that cars do not--symmetry of matter. Materialwise, they are consistent. Imagine a plane slicing through a rock dividing it into two--slicing at any angle. The material on both sides of the plane will always be of the same type of material possessing the same properties. This is why a rock sliced in half results in 2 rocks--not 2 half rocks. That is not true for cars because I can slice only the tire and have rubber on one side and the remainder of the car (glass, metal, etc) on the other side. Slicing a car in half results in 2 half-cars

    Slicing a continent behaves like slicing a rock. You will end up with 2 continents: not 2 half continents because a continent is an organizational structure which we determine based on an arbitrary selection process (such as elevation above sea level). Since a continent is purely a conceptual organization, that means every point within it has exactly the same property value: inside. It is materially consistent just like a rock (or cookie).

    You can, however, have half an Oreo Cookie.

    Obviously the cookie is made of an exotic form of matter. Other substances, like water or salt, can be divided almost indefinitely (until you get down to a single molecule) without losing their properties. Not so with cookie matter. A chocolate chip cookie can be broken down only so far before it ceases being a chocolate chip cookie, and becomes just a plain cookie. This can happen even at centimetre scales. Some cookies have a directionality to them. Oreos, for example, when broken radially maintain their "Oreo-ness". However, when broken perpendicular to the axis, an Oreo can lose its "Oreo-ness" and transform into a simple chocolate cookie.

    I heard that there was some study done on this phenomenon, however the lab was plagued by a large, blue-furred creature who would yell "COOKIE!", and vanish with all of the sample materials.
