There is nowhere on earth that anyone or any instrumentation will ever see light bend.
What exactly do you mean when you write of light bending? Are you saying that light behaves like a particle, traveling in a straight line from its source until it strikes a surface?
The common explanation of how light is not (just) a particle and diffraction works conceptually is the double slit experiment. And you can easily find tons of material on it, often with pictures that show the difference between 'particle' (no bending) and 'wave' (bending in the sense that there does not need to be a straight line of uninterrupted medium between the source of the light and the surface it hits) like this:
What you would expect from a particle:
What the experiment actually produces:

So, are you saying the lower picture is misleading, or is the effect it shows not what you refer to with the term bending? In the former case, how is the diffraction pattern explained? Do you have any good material for an alternate explanation?
Edit: Hadn't watched the video previously, but the laser beam producing a disk instead of a point is not a double slit, but it shows the same kind of 'bending'.
