So the glass of water acts just like a curved mirror. It bends the rays of light towards each other, and if the focal point of the two rays is in front of the arrow, then what you see is a reversed image. You can see this effect in a magnifying mirror or magnifying glass. As you move away, suddenly the image you see will flip.
Let me see if I can find a graphic... google.... aha!

"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great
