Brb buying propylene glycol! Turns out there are vape-shops that sell the glycol, the water, and the paraphernalia to mix them! There is some food coloring left from the last party. Will have to source some glass plates still :-)

The pg is already in the food coloring. What you need are differential evaporation rates, so I would experiment with mixing water and/or alcohol with one color and then leave the other alone.

You can do this with milk and liquid food coloring. Our kids do it at nursery school.
