Any person wondering “is that a cucumber?” does not appreciate the great utility of CT density. A cucumber is mainly water and so would appear grey on CT but this vegetable is black and so contains a lot of air. Can you think of a vegetable that is a similar shape to a cucumber but is a lot less dense? If you can then you have just learnt one answer to this quiz question. The next thing to learn is that this vegetable is best taken orally!
