Red Green Blue Filters
The age old use of Red Green Blue filters to seperate and blend action was used to make milk blend white from 3 exposures through the filters.

That technique may be "age old", but it's the first time I've seen it. Very cool and colorful. Quite an eye catching image!

Wow, thanks Greg! 6 years between comments!! I had almost forgotten about this image!!
The theory is "anything that holds still through all three filters, renders normally" or as we humans see things with visible light, Hence the glass and the milk at the bottom all look "normal". But you see three strands of milk exposed though red, green then blue filters and they seperate out. There is a thin layer of red milk, the distinct layer of green milk and the distinct layer of blue milk.
It's a fun technique. There used to be those who built "Harris Shutters" out empty of Kodak Test Strip boxes. They would build a hoder to hold the red, green and blue filters, then drop the drop the filters though the box that was attached to the camera lens, that enabled use of the technique outside on moving subjects and could produce some outstanding results.
I used to have some examples using the harris shutter, sunset highlights on lakes and rivers were espicially effective.
Google "Harris Shutter" for examples...
