Zeno's Paradoxical Chocolate Bar

Zeno's Paradox (see link) is concerned with the business of an arrow that never reaches its target. (even though it does)

Zeno's Paradoxical Chocolate Bar brings joy to all of those who sit together in discussion of the famous conundrum. It's a simple bar of chocolate that resembles a long arrow once it has been released from its cardboard carton and foil wrapper.

On closer examination, the arrow can be seen to have a set of parallel lines running down the entire length of its shaft. The first one of these is half-way along the arrow. Participants begin the process of eating the arrow by breaking it here. The half with no lines on it is now divided evenly between all of the guests. The remaining half is then broken into two pieces at the next line and again divided evenly.

This process is repeated until the lines are so small that a magnifying glass and a razor blade are required to separate the pieces, and still it continues, because as long as there is half of something, then mathematics tells us that there is another half remaining to be divided again.

Eventually the participants resolve the paradox, the proof of this being that no chocolate remains. All are sworn to secrecy as to the outcome of the puzzle being one of the conditions of purchase required by the makers of the notorious Zeno's Paradoxical Chocolate Bar.
