Oil & Water 3.0

The idea of the trick: 
The magician shows four red-faced cards and four black-faced cards. He alternates these cards: one red, one black, one red, etc. 
Like oil and water do, they separate mysteriously: the red cards gather on one side, the blacks on the other side! 
Thanks to the magic, colors mix and separate by themselves... 
At each step of the trick, things become more and more impossible. 
The climax is incredible: the magician does NOTHING and the magic happens! 

If you don't know anything about "Oil & Water": 
You will own a mass destruction weapon with this multi-phase routine. 

If you already have your own version of this great classic of card magic: 
You can complete it by integrating one or several phases. 

In every case: 
This completely revolutionary climax (no sleight of hands for this phase!) will bring your Oil & Water routine to unsuspected heights!
