The magician borrows two wedding rings from a couple present and puts the rings on a padlock. This is a combination lock with four number wheels, each with the numbers 1-10. The number wheels are twisted and the rings are locked.
With the number of number combinations, it is impossible to free the rings if you do not know the correct sequence of numbers. The couple name the wedding date, this is set and the lock releases the rings!
Immediately, the effect could be repeated with another couple and another date.
Or you tie up a spectator's car key, they take out their car documents and the lock opens as soon as the MOT date of the car to which the key belongs is set!
The lock works for you and can be let out without hesitation. Nevertheless, everything is very simple so that you only have to concentrate on the presentation!
