Water
It just does not bend, its common sense Edit: light does bend, but it is so fast, it doesn't look like it's bending. If you shoot a laser into the water, you can see that it bends as it touches the surface. Also, you can see that from the night sky. Stars' gravity can bend lights, sometimes stars appears to be bigger, or smaller than it really is. But remember Newton's Laws. A body set in motion will continue ...
Static electricity.
refraction causes it to bend

No. Water droplets bend light to make rainbows.
as soon as it gets printed, immediately bend it the other way.
The speed of water at a river bend flows much faster and deeper on the outside of the bend. On the inside of the bend the velocity is much slower and shallower.

Spray water at the path of the laser and it should reveal the ray.
The ray will bend towards the normal.
As the river flows around the outside of the bend, it accelerates just like when a car goes around a bend. The water, like a car, is pulled toward the outside of the bend through centripetal force (which is why road bends are often banked). The same thing happens to the water surface. It actually rises around the outside of the bend. This higher elevation of the water surface means that the water on the outside of the bend is slightly deeper than the inside. Since water always tries to seek a level surface, the water on the outside of the bend actually flows downward, along the bottom and comes back up on the inside of the bend. This secondary current pushes material from the outside of the bend back up on the inside of the bend - and that's where sand bars come from. So the combination of accelerated flow around the outside combined with the secondary current moving downward erodes the outside of the river bend.
