The Dual Principle ('You Do As I Do')
Two packs, one secret glimpse, an impossible match.
Definition
In 'You Do As I Do' mysteries each person works with their own pack, mirroring the performer's actions. A single secret — usually a glimpse and a switch of position — guarantees both 'freely chosen' cards match.
Why it fools people
Because the spectator performs the same fair-looking actions you do, they vouch for the procedure. They never suspect that one quiet glimpse has predetermined the coincidence.
What it lets you do
- Two-person coincidences
- Hands-off-feeling mysteries
- Strong closers for casual settings
Beginner drills
Glimpse and mirror
With two packs, glimpse your spectator's bottom card during a natural tilt, then guide both selections so the known card resurfaces as the match.
Success: Both cards match and the spectator feels they did it themselves.
Common mistakes
- A glimpse that lingers.
- Rushing the exchange of packs.
