Item Number: MK2187
Make a bet that gives you very bad odds, only a 20% chance you'll win! Place a bill into a wooden wallet, and have a spectator lock it in with a padlock. The bill remains visible through 2 holes in the wallet at all times! Show 5 keys and explain that only 1 of these keys will open the lock. They can win the money if they have the key that opens the lock. Mix the keys up and have them freely selected by 4 different people. Each person attempts to open the lock and all fail! Finally the performer opens the lock with the remaining key that was not selected!
