Instructions for creation (what i did; may not be the most efficient)
1 Add maple syrup to an empty graduated cylinder; take care to avoid spilling it on the sides (I used a pipette for this).
2 Add one drop of blue food coloring to about 100 ml of water.
3 Pour in some of the blue water using a pipette if wanted (if you get it on the sides, let the cylinder dry after)
4 Pipette or pour in some dish soap, it should settle below the water without many bubbles, though it may form a gradient (which is pretty too.)
5 Use a pipette to suction off any soap bubbles that may have formed on the water surface.
6 Pour in vegetable oil
7 Pour in olive oil. The olive oil should float above the vegetable oil, but it may form a gradient. There will be bubbles in the oil; these should dissipate in a few hours.
8 Pipette in some more blue water—it should sink, and the oil will slow it down enough so it won't mix with the now turquoise soap-water gradient.
9 Add some red food coloring to some cooking alcohol.
10 Pipette in the alcohol; it should sink through the oil in a similar way and settle above the pure water layer. There may be a short purple transition zone.
11 Let the cylinder settle for two or three hours.
