Water acts like a magnifying glass.

It's very simple. The water acts like a magnifying glass, giving the illusion that the object is bigger than it is. It also causes the object to look like it's a little off to one side, which I believe is called "defraction", but I'm not sure, you'll have to double check that. But what it means is, the water causes the light passing through it to "bend", making an object look slightly out of alignment with it's actual location. Some "desert Island" movies will talk about it when you see the characters trying to spear fish from the beach or a rock, because they have to allow for "defraction" when trying to spear the fish. Hope I was of some help.

When you look at something in water, the light from it that gets to your eye must pass through the water surface separating the air and water. The rays of light from the water bend towards the surface as they enter the air. (This is called refraction.) In fact, the more the rays are angled to the surface, the more they bend. Because of all this, the angle you have to move your eye to see the full object gets bigger and therefore the object in the water looks bigger. The refraction is directly responsible for the apparent bend in the object.
