Cool physics video

The lights not bending, its reflecting.. :). Sorry i just wanted to be apart the gang.. this is a gang right? jk.
-
50% of the people that come on this video: this isn't bending the light. it's titty inferno reflection. i did not read the video description. admire my basic science information on the intrawebz.

Love how 80% of the comments were about how this "isn't light bending". Jeez, it's just a title.
Anyway, neat trick you got there. I remember doin' that at school with a couple mates of mine back when science was fun and not a chore.

@chronosifter id like to do this for my science fair.. what are the variables?
-
it's not bending of light
it's bending of water because of gravity
-
Just like optical fiber.
-
the same thing happens with the optical fiber

This is not bending light, it is: total internal reflection. It occurs when the light vector is at too large of an angle away from the surface normal at point of contact to pass through the boundary. Different mediums have different refractive indices, which is what determines too large of an angle. Calculating those at each point of contact is surprisingly simple, in computer graphics we use it for both reflection and refraction in transparent materials (liquids, glass, etc...).

@chronosifter In video description you will find "Total internal reflection". It's been there since june 2009

Not bending, try "inner reflection" :)
