Can you manipulate destiny?!

LUCKY STRINGS

A baffling game they simply can't win!

Five strings extend from an envelope, but only one string is attached to the winning bell at the bottom. Allow your spectator to choose four of the strings, and the final string remains for you. Pull each of the selected strings upward, and show that they are all loose strings - none of them are attached to the winning bell. The single string they left for you is the winner! Every selection is freely made by the spectator. Even if they decide to change strings midway, they still cannot find the winning string.

Everyone is fascinated by the concept of destiny, and that is clearly the theme of this baffling magic trick!
