David Regal Presents – The Hummer Principle
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!
