It seems that their urine-to-water conversion machine is malfunctioning...

The 2:26 glitch to me looks like a mpeg transmission error which caused the decoder to shift the chroma to the right.

Not to get too technical, basically video transmission does not work with RGB pixels (red/green/blue intensities) but with luminance (luma) and chrominance (chroma). Luminance being basically a black and white picture of light intensities, and chrominance being a picture just of colour information. When the glitch occurs, the entire colour information shifts to the right and you can see a blob of brown colour to the right of the cup. There is also a shadow to the right of the fold in the backdrop. The video stabilizes after having a further glitch manifesting as scattered blocks.

See here for example of what is luma/chroma: http://images.digitalmedianet.com/2007/Week_9/pu0br08v/story/photo_lum a_chroma.jpg

What you saw in the video was the colour being shifted momentarily.

In the movie if you pause it at 2:26 the bag looks empty and there is an orange square there to the right. Are we being tricked here? is there really liquid in that bag or are we seeing some sort of video composite magic?

I love when he rattles off the equation for a successful coffee cup angle..you need a physics phd just to be these guys' secretaries.
