THERE IS A VITAL PIECE OF INFORMATION YOU NEED TO KNOW about setting this lock.
If you play with the lock before watching the instructions, you may damage it.

The FORT KNOX LOCK is simple to operate, very deceptive- and can be set to work with thousands of combinations!
How can that be??

Watch Peter perform THREE different routines with Dirk in the demo video above.
These are only the routines that we've come up with.
Once you know that ingenious secret, you will no doubt come up with some great routines of your own, too!

ROUTINE #1
The spectator FREELY CHOOSES a set of three digits.
To make it completely fair, the spectator is asked to do several simple mathematical calculations with those numbers, in order to end up with a four-digit number.
When the spectator dials the tumblers to those numbers- THE LOCK OPENS!

ROUTINE #2
The spectator FREELY CHOOSES ANY NUMBER of digits- two digits, five digits, ten digits, etc.
To make it completely fair, the spectator is asked to do several simple mathematical calculations with those numbers, in order to end up with a two-digit number.
Then the spectator can FREELY CHOOSE any other two digits, to end up with a four-digit number.
When the spectator dials the tumblers to those numbers- THE LOCK OPENS!

ROUTINE #3 (the most spectacular!)
The spectator is asked to concentrate on a specific century in history.
Peter chose the 20th Century (1900-1999), but this works with any century.
The spectator then FREELY CHOOSES a specific year in that century.
When the spectator dials the tumblers to those numbers- THE LOCK OPENS!
But wait- there's more!
The spectator is asked if he would have chosen a different number.
He speaks that number out loud- then tries the lock again.
IT OPENS!
And yet, if the tumblers are placed in ANY OTHER POSITIONS, the lock remains locked!

So think about this for a second.
This lock can be set to open at thousands of different tumbler combination.
This lock can be handled by the spectator during the effect.
And this lock can even open TWO OR MORE different combinations during the same routine!

It seems impossible!
But there is no force of any 4-digit pre-set numbers!
No electronics, magnets, buttons, switches, wires, gravity switch, timers, smoke or mirrors!
Nothing is added or taken away- except maybe your spectator's breath!
