David Regal - The Hummer Principle (Video + PDF)

Imagine this: your spectator mixes ANY cards face-up and face-down while YOUR back is turned. Then:

Miracle 1: You KNOW how many cards are reversed. Impossible!

Miracle 2: You CAUSE the red cards to separate from the black!

Miracle 3: You ASK the spectator to THINK of a ANY card...

and what happens next is 100% impossible!
