First off you didn't have to buy just Diet Coke.  It could have been any of
the Coke products.

Secondly, the effect works by fooling the brain.  The lenses are not polarized,
just one darker than the other.  The darker lens causes the image to be
delayed in the brain, causing the 3D effect.  Notice how the stuff moved
from right to left.  That was part of it.

I wouldn't be surprised if a neutral density filter would also to the job.
