why a stick in water seems cooked

We are seeing an image from below the water that is above the real position of the stick - due to the way light is refracted towards the viewer as it leaves the water surface.
The same effect happens in a swimming pool - the water looks shallower than it really is because the image of the pool bottom appears higher through the water than it really is.
Light is refracted away from the normal line into a more horizontal direction as it passes out through the water surface .. so light from the stick below water enters the viewer's eye less steeply than it otherwise would. As the brain locates the position of an image from the direction rays have as they enter the eye, rays entering from a more horizontal direction are judged to have come from a source that is higher up in the water than it really is.
Because light from the stick part above water is not affected by refraction, the brain interprets the whole stick as bent (slightly upwards) at the point it enters the water.

Explanation:
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
