24. Coca-Cola Recipe Vault, United States

Coca-cola is an iconic and classic drink that has been around since the 1800s. Although the drink is known around the world, the recipe is one of America's greatest secrets. Trying to steal this formula would be nearly impossible with the complicated vault that has a hand scanner, armed guards, and a combination.

It would probably be easier to steal the Declaration of Independence like Nicolas Cage showed everyone. They should make another movie showing people how to steal the Coca-Cola formula. Some things are better left to the imagination.
