I have never been that big of a fan of Oil and Water plots, but this one has a great presentation!
This version is super visual and truly is easy to do. This could be done walk around, or in a formal
parlor/close up set. Because of the obvious color, kids that don't know playing cards understand
what is happening. If you are looking at a strong 5 minute card piece that has nothing to do with
"pick a card", this is great. and the justification for using a separate deck after this effect is
justified as well (you wouldn't want to perform with a half red and half blue deck would you?).
I don't know how long this has been out, but I believe this has been overlooked by many
magicians and has disappeared in the vast amount of magic that has come out in the past several
years.
