The watercolor paper gives a softer, mottled effect, whereas the Yupo paper is glossy and imparts brighter colors to your designs.  You can use layering as it dries, as well as a straw to blow the ink over it after you’ve applied the 90% rubbing alcohol with a dropper.  You can also move the paper around to make drips and designs.

Chromatography

This is a fun process that you could link to science lessons in your classroom, based on the idea of chromatography.1 This means that different colors have molecules that separate out based on how much they are absorbed by the paper.  Using a coffee filter, we applied washable markers to the paper and stuck in a cup of water part way.  The colors wicked up and separated out.
